PJ7_GPIO63/XCLKIN

The M3 GPIO Mux also contains an alternate muxing mode. The proper bits in the Alternate Peripheral

Select (GPIOAPSEL) register must be set to access these muxing options. The Digital Function

(GPIOPCTL) register can then be used to select the mux option.

4.1.3 Functional Description

Each GPIO port is a separate hardware instantiation of the same physical block (see

microcontroller contains nine ports and therefore nine of these physical GPIO blocks. Note that not all pins

may be implemented on every block. Some GPIO pins can function as I/O signals for the on-chip

peripheral modules.
