5.4 GPIO Pins and Peripheral Mode Functions
GPIO Function
All eight GPIO pins in each GPIO port have access to a common set of low-level peripheral functions that can use GPIO pins as inputs or outputs:
• Output signal streams from Pulse Trains 0 through 7 (three options for each pin)
• Input/output signals (depending on configured timer mode) for the 32-bit Timer (0, 1, 2, and 3) modules
Note
The following tables apply to both Compact and Standard Pin Layouts; however, only P0, P1, and P2 are available for the Compact Pin Layout.
