The following list describes the
contents of each column in the Pin Attributes table:
- BALL NUMBER: Ball numbers assigned to each
terminal of the Ball Grid Array package.
- BALL NAME: Ball name assigned to each terminal
of the Ball Grid Array package (this name is typically taken from the primary
MUXMODE 0 signal function).
- SIGNAL NAME: Signal name(s) of all dedicated
and pin multiplexed signal functions associated with a ball.
Note:
The Pin Attributes
table, defines the pin multiplexed signal functions implemented at the
pin and does not define secondary multiplexing of signal functions
implemented in device subsystems. Secondary multiplexing of signal
functions are not described in this table. For more information on
seconadry multiplexed signal functions, see the respective peripheral
chapter of the device TRM.
- PIN CONTROL REGISTER: Name
of pin control register. Reference the device Technical Reference Manual.
- PIN CONTROL
ADDRESS:Address of pin control register. Reference the device Technical
Reference Manual.
- MUX MODE: The MUXMODE value associated with each
pin multiplexed signal function:
- MUXMODE 0 is the primary
pin multiplexed signal function. However, the primary pin multiplexed
signal function is not necessarily the default pin multiplexed signal
function.
Note:
The value found in
the MUX MODE AFTER RESET column defines the default pin
multiplexed signal function selected when MCU_PORz is
deasserted.
- MUXMODE values 1 through
15 are possible for pin multiplexed signal functions. However, not all
MUXMODE values have been implemented. The only valid MUXMODE values are
those defined as pin multiplexed signal functions within the Pin
Attributes table. Only valid values of MUXMODE should be used.
- Bootstrap defines SOC
configuration pins, where the logic state applied to each pin is latched
on the rising edge of PORz_OUT. These input signal functions are fixed
to their respective pins and are not programmable via MUXMODE.
- An empty box or "-" means
Not Applicable.
- TYPE: Signal type and direction:
- I = Input
- O = Output
- IO = Input, Output, or
simultaneously Input and Output
- IOD = Input, Output, or
simultaneously Input and Output, with open-drain output function
- IOZ = Input, Output, or
simultaneously Input and Output, with three-state output function
- OZ = Output with
three-state output function
- A = Analog
- PWR = Power
- GND = Ground
- CAP = LDO Capacitor.
- DSIS: The deselected input state (DSIS) indicates the
state driven to the subsystem input (logic "0", logic "1", or "pad" level) when
the pin multiplexed signal function is not selected by MUXMODE.
- 0: Logic 0 driven to the
subsystem input.
- 1: Logic 1 driven to the
subsystem input.
- pad: Logic state of the
pad is driven to the subsystem input.
- An empty box or "-" means
Not Applicable.
- BALL STATE DURING RESET (RX/TX/PULL):
State of the terminal while MCU_PORz is asserted, where RX defines the state of
the input buffer, TX defines the state of the output buffer, and PULL defines
the state of internal pull resistors:
- RX (Input buffer)
- Off: The input
buffer is disabled.
- On: The input
buffer is enabled.
- TX (Output buffer)
- Off: The output
buffer is disabled.
- Low: The output
buffer is enabled and drives VOL.
- PULL (Internal pull
resistors)
- Off: Internal
pull resistors are turned off.
- Up: Internal
pull-up resistor is turned on.
- Down: Internal
pull-down resistor is turned on.
- An empty box or "-" means
Not Applicable.
- BALL STATE AFTER RESET (RX/TX/PULL):
State of the terminal after MCU_PORz is deasserted, where RX defines the state
of the input buffer, TX defines the state of the output buffer, and PULL defines
the state of internal pull resistors:
- RX (Input buffer)
- Off: The input
buffer is disabled.
- On: The input
buffer is enabled.
- TX (Output buffer)
- Off: The output
buffer is disabled.
- SS: The subsystem
selected with MUXMODE determines the output buffer state.
- PULL (Internal pull
resistors)
- Off: Internal
pull resistors are turned off.
- Up: Internal
pull-up resistor is turned on.
- Down: Internal
pull-down resistor is turned on.
- An empty box or "-" means
Not Applicable.
- MUX MODE AFTER RESET: The value
found in this column defines the default pin multiplexed signal function after
MCU_PORz is deasserted.
An empty box means Not
Applicable.
- I/O VOLTAGE VALUE: This column describes
I/O operating voltage options of the respective power supply, when applicable.
An empty box or "-" means Not Applicable.For more information, see
valid operating voltage range(s) defined for each power supply in
Recommended Operating Conditions.
- POWER DOMAIN: The power supply of the associated
I/O, when applicable. An empty box or "-" means this description is not
applicable.
- HYS: Indicates if the input buffer associated with
this I/O has hysteresis:
- Yes: With hysteresis
- No: Without
hysteresis
- An empty box or "-" means
Not Applicable.
For more information, see
the hysteresis values in Electrical Characteristics.
- BUFFER TYPE: This column defines the buffer
type associated with a terminal. This information can be used to determine which
Electrical Characteristics table is applicable.
An empty box or "-" means Not
Applicable.
For
electrical characteristics, refer to the appropriate buffer type table in
Electrical Characteristics.
- PULL UP/DOWN TYPE: Indicates the
presence of an internal pullup or pulldown resistor. Pullup and pulldown
resistors can be enabled or disabled via software.
- PU: Internal pull-up
- PD: Internal
pull-down
- PU/PD: Internal pull-up
and pull-down
- An empty box or "-" means
No internal pull.
Note:
Configuring two pins to
the same pin multiplexed signal function is not supported as it can
yield unexpected results. This can be easily prevented with the proper
software configuration.
Note:
When a pad is set into a
multiplexing mode which is not defined by pin multiplexing, that pad’s
behavior is undefined. This should be avoided.
