PM2
Caution If a pin is set as an analog input port, not the pin level but “0” is always read.
When using the ANI0/P20 to ANI7/P27 pins for analog input port, set PM20 to PM27 to 1. The output latches of
P20 to P27 at this time may be 0 or 1.
If PM20 to PM27 are set to 0, they cannot be used as analog input port pins.
PM2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
ANI0/P20 to ANI7/P27 pins are as shown below depending on the settings of ADPC, ADS, and PM2.
