Set in each port I/O, buffer, pull-up resistor is also valid for alternate functions.
Note 1. Input of A/D converter is not supported.
Note 2. Each pin can be specified as digital I/O port by setting port mode control register x (PMCx) (Can be specified in 1-bit
units).
Note 3. This pin is used for connection between the MCU and RF transceiver. For details, refer to CHAPTER 2 CONNECTION
BETWEEN MCU AND RF TRANSCEIVER
.
Note 4. Each pin can be specified as either digital or analog by setting the A/D port configuration register (ADPC).
