RL78/G1A CHAPTER 4 PORT FUNCTIONS

4.3.6 Port mode control registers (PMCxx)
These registers set the digital I/O/analog input in 1-bit units.
Port mode control registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to FFH.

PMCmn
Pmn pin digital I/O/analog input selection
(m = 0, 1, 3 to 5, 7, 12; n = 0 to 5)
0 Digital I/O (alternate function other than analog input)
1 Analog input
Cautions 1. Select input mode by using port mode registers 0, 1, 3 to 5, 7, 12 (PM0, PM1, PM3 to PM5, PM7,
PM12) for the ports which are set by the PMCxx register as analog input.
2. Do not set the pin set by the PMCxx register as digital I/O by the analog input channel
specification register (ADS).
3. Be sure to set bits that are not mounted to their initial values.
