GPIO MUX

On the 280x, the GPIO MUX can multiplex up to three independent peripheral signals on a single GPIO pin in addition to providing individual pin bit-banging IO capability. The GPIO MUX block diagram per pin is shown in Figure 6-16. Because of the open-drain capabilities of the I2C pins, the GPIO MUX block diagram for these pins differ. See the TMS320x280x, 2801x, 2804x DSP system control and interrupts reference guide for details.

TMS320F2809 TMS320F2808 TMS320F2806 TMS320F2802 TMS320F2801 TMS320C2802 TMS320C2801 TMS320F28016 TMS320F28015 gpiomux_prs230.gif
x stands for the port, either A or B. For example, GPxDIR refers to either the GPADIR and GPBDIR register depending on the particular GPIO pin selected.
GPxDAT latch/read are accessed at the same memory location.
Figure 6-16 GPIO MUX Block Diagram

The 280x supports 34 GPIO pins. The GPIO control and data registers are mapped to Peripheral Frame 1 to enable 32-bit operations on the registers (along with 16-bit operations). Table 6-16 shows the GPIO register mapping.

This table pertains to the 2808 device. Some peripherals may not be available in the 2809, 2806, 2802, or 2801 devices. See the pin descriptions for more detail.
The word "Reserved" means that there is no peripheral assigned to this GPxMUX1/2 register setting. Should it be selected, the state of the pin will be undefined and the pin may be driven. This selection is a reserved configuration for future expansion.
GPxMUX1/2 refers to the appropriate MUX register for the pin; GPAMUX1, GPAMUX2 or GPBMUX1.

The user can select the type of input qualification for each GPIO pin via the GPxQSEL1/2 registers from four choices:

  • Synchronization To SYSCLKOUT Only (GPxQSEL1/2 = 0,0): This is the default mode of all GPIO pins at reset and it simply synchronizes the input signal to the system clock (SYSCLKOUT).
  • Qualification Using Sampling Window (GPxQSEL1/2 = 0,1 and 1,0): In this mode the input signal, after synchronization to the system clock (SYSCLKOUT), is qualified by a specified number of cycles before the input is allowed to change.
  • TMS320F2809 TMS320F2808 TMS320F2806 TMS320F2802 TMS320F2801 TMS320C2802 TMS320C2801 TMS320F28016 TMS320F28015 qual_samp_prs230.gifFigure 6-17 Qualification Using Sampling Window
  • The sampling period is specified by the QUALPRD bits in the GPxCTRL register and is configurable in groups of 8 signals. It specifies a multiple of SYSCLKOUT cycles for sampling the input signal. The sampling window is either 3-samples or 6-samples wide and the output is only changed when ALL samples are the same (all 0s or all 1s) as shown in Figure 5-11 (for 6-sample mode).
  • No Synchronization (GPxQSEL1/2 = 1,1): This mode is used for peripherals where synchronization is not required (synchronization is performed within the peripheral).

Due to the multi-level multiplexing that is required on the 280x device, there may be cases where a peripheral input signal can be mapped to more then one GPIO pin. Also, when an input signal is not selected, the input signal will default to either a 0 or 1 state, depending on the peripheral.
