I/O Pads and Pin Multiplexing
16.8.1 Pad Configuration Registers for Application Pins
Table 16-11 lists the configuration registers associated with the device pins.
(1)
Pins are referred either by number or by the GPIO mapped to that pin. Functionalities available on a pin are not limited to that
name. Refer to the pin-mux table for all possible functional mapping.
(2)
These four pins are dedicated for the external SPI serial flash. These cannot be used or shared in any way for other functions.
