3.7.1 Device Reset, NMI and JTAG

Table 3-5 Reset, NMI and JTAG Terminal Functions

SIGNAL TYPE(1) PULL(2) POWER
GROUP(4) 		DESCRIPTION
NAME NO.
RESET
RESET K14 I — B Device reset input
NMI J17 I IPU B Non-Maskable Interrupt
RESETOUT / UHPI_HAS / GP6[15] T17 O(3) CP[21] C Reset output
JTAG
TMS L16 I IPU B JTAG test mode select
TDI M16 I IPU B JTAG test data input
TDO J18 O IPU B JTAG test data output
TCK J15 I IPU B JTAG test clock
TRST L17 I IPD B JTAG test reset
EMU0 J16 I/O IPU B Emulation pin
EMU1 K16 I/O IPU B Emulation pin
(1) I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal.
Note: For multiplexed pins where functions have different types (ie., input versus output), the table reflects the pin function direction for that particular peripheral.
(2) IPD = Internal Pulldown resistor, IPU = Internal Pullup resistor. CP[n] = configurable pull-up/pull-down (where n is the pin group) using the PUPDENA and PUPDSEL registers in the System Module. For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown resistors are required, see the Device Configuration section. For electrical specifications on pullup and internal pulldown circuits, see the Device Operating Conditions section.
(3) Open drain mode for RESETOUT function.
(4) This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power supply DVDD3318_C.
(5) GP8[0] is initially configured as a reserved function after reset and will not be in a predictable state. This signal will only be stable after the GPIO configuration for this pin has been completed. Users should carefully consider the system implications of this pin being in an unknown state after reset.
