When using the ANI0/P20 to ANI5/P25 pins for analog input port, set PM20 to PM25 to 1. The output latches of
P20 to P25 at this time may be 0 or 1.
If PM20 to PM25 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 this register to FFH.
ANI0/P20 to ANI5/P25 pins are as shown below depending on the settings of PF2, ADPC0, PM2, and ADS.
