GPIO_MUX1

One-hundred and thirty-six pins of the GPIO_MUX1 block can be selectively mapped through corresponding sets of registers to all Cortex-M3 peripherals, to all C28x peripherals, to 136General-Purpose Inputs, to 136 General-Purpose Outputs, or a mixture of all of the above. The first 64 pins of GPIO_MUX1 (GPIO0–GPIO63) can also be mapped to 12 ePWM Trip Inputs, 6 eCAP inputs, 3 External Interrupts to the C28x PIE, and the C28x STANDBY Mode Wakeup signal (LMPWAKE). Additionally, each GPIO_MUX1 pin can have a pullup enabled or disabled. By default, all pullups and outputs are disabled on reset, and all pins of the GPIO_MUX1 block are mapped to Cortex-M3 peripherals (and not to C28x peripherals).

Figure 6-15 shows the internal structure of GPIO_MUX1. The blue blocks represent the Master Subsystem side of GPIO_MUX1, and the green blocks are the Control Subsystem side. The grey block in the center, Pin-Level Mux, is where the GPIO_MUX1 pins are individually assigned between the two subsystems, based on how the configuration registers are programmed in the blue and green blocks (see Figure 6-16 for the configuration registers).

Pin-Level Mux assigns Master Subsystem peripheral signals, Control Subsystem peripheral signals, or GPIOs to the 136 GPIO_MUX1 pins. In addition to connecting peripheral I/Os of the two subsystems to pins, the Pin-Level Mux also provides other signals to the subsystems: XCLKIN and GPIO[S:A] IRQ signals to the Master Subsystem, plus GPTRIP[12:1] and GPI[63:0] signals to the Control Subsystem. XCLKIN carries a clock from an external pin to USB PLL and CAN modules. The 17 GPIO[S:A] IRQ signals are interrupt requests from selected external pins to the NVIC interrupt controller. The 12 GPTRIP[12:1] signals carry trip events from selected external pins to C28x control peripherals—ePWM, eCAP, and eQEP. Sixty-four GPI signals go to the C28x LPM GPIO Select block where one of them can be selected to wake up the C28x CPU from Low-Power Mode. One-hundred and thirty-six (136) GPI signals go to the C28x QUAL block where they can be configured with a qualification sampling period (see Figure 6-16).

The configuration registers for the muxing of Master Subsystem peripherals are organized in 17 sets (A–S), with each set being responsible for eight pins. The first nine sets of these registers (A–J) are programmable by the Cortex-M3 CPU through the AHB bus or the APB bus. The remaining sets of registers (K–S) are programmable by the AHB bus only. The configuration register for the muxing of Control Subsystem peripherals are organized in five sets (A–E), with each set being responsible for up to 32 pins. These registers are programmable by the C28x CPU through the C28x CPU bus. Figure 6-16 shows set A of the Master Subsystem GPIO configuration registers, set A of the Control Subsystem registers, and the muxing logic for one GPIO pin as driven by these registers.

For each of the 8 pins in set A of the Cortex-M3 GPIO registers, register GPIOPCTL selects between 1 of 11 possible primary Cortex-M3 peripheral signals, or 1 of 4 possible alternate peripheral signals. Register GPIOAPSEL then picks one output to propagate further along the muxing chain towards a given pin. The input takes the reverse path. See Table 6-27 and Table 6-28 for the mapping of Cortex-M3 peripheral signals to GPIO_MUX1 pins.

Similarly, on the C28x side, GPAMUX1 and GPAMUX2 registers select 1 of 4 possible C28x peripheral signals for each of 32 pins of set A. The selected C28x peripheral output then propagates further along the muxing chain towards a given pin. The input takes the reverse path. See Table 6-29 for the mapping of C28x peripheral signals to GPIO_MUX1 pins.

In addition to passing mostly digital signals, four GPIO_MUX1 pins can also be assigned to analog signals. The GPIO Analog Mode Select (GPIOAMSEL) Register is used to assign four pins to analog USB signals. PF6_GPIO38 becomes USB0VBUS, PG2_GPIO42 becomes USB0DM, PG5_GPIO45 becomes USB0DP, and PG6_GPIO46 becomes USB0ID. When analog mode is selected, these four pins are not available for digital GPIO_MUX1 options as described above.

Another special case is the External Oscillator Input signal (XCLKIN). This signal, available through pin PJ7_GPIO63, is directly tied to USBPLLCLK (clock input to USB PLL) and two CAN modules. XCLKIN is always available at these modules where it can be selected through local registers.

NOTE

For GPIO_MUX1 pins PF6_GPIO38 and PG6_GPIO46, only the corresponding USB function is available on silicon revision 0 devices (GPIO and other functions listed in Table 4-1 are not available).
