CHAPTER 4 I/O PORTS
Table 4.5-4 summarizes the operating modes of the pin of port 5.
Note:
If the pull-up resistor is selected by using the pull-up setting register, the pin state will be "H" level
(pull-up state) instead of Hi-Z in stop mode (SPL = 1). During a reset, however, the pull-up is invalid
with the pin remaining at Hi-Z.

Pin name Normal operation, sleep, stop (SPL = 0) Stop (SPL = 1) At a reset
P50/PWM General-purpose I/O port further may serve I/O for peripherals Hi-Z Hi-Z
SPL : Pin state setting bit of standby control register (STBC: SPL)
Hi-Z: High impedance
