8.9.15 General-Purpose Input/Output (GPIO) MUX

The GPIO MUX can multiplex up to three independent peripheral signals on a single GPIO pin in addition to providing individual pin bit-banging I/O capability.

The device supports 45 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 8-38 shows the GPIO register mapping.

(1) 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.

(3) The eQEP2 peripheral is not available on the 80-pin PN or PFP package.
(4) To enable the USB functionality on GPIO26 (USB0DP, positive differential half of the USB signal) and GPIO27 (USB0DM, negative differential half of the USB signal), set the USBIOEN bit in the GPAC
