RL78/G10 CHAPTER 4 PORT FUNCTIONS

4.6.2 Notes on specifying the pin settings
For an output pin to which multiple alternate functions are assigned, the output of the unused alternate functions must
be set to its initial state so as to prevent conflicting outputs. This also applies to the functions assigned by using the
peripheral I/O redirection register (PIOR). For details about the alternate output function, see 4.5 Register Settings
When an Alternate Function Is Used.
No specific setting is required for input pins because the output of their alternate functions is disabled (the buffer output
is Hi-Z).
Disabling the unused functions, including blocks that are only used for input or do not have I/O, is recommended for
lower power consumption.
