(4) 8-bit A/D conversion result register (ADCRH)
This register is an 8-bit register that stores the A/D conversion result. It stores the higher 8 bits of a 10-bit
resolution result.
ADCRH can be read by an 8-bit memory manipulation instruction.
Reset signal generation makes ADCRH undefined.

(5) Port mode register 2 (PM2) and port mode control register 2 (PMC2)
When using the when the P20/ANI0/TI000/TOH1, P21/ANI1/TI010/TO00/INTP0, P22/ANI2, and P23/ANI3 pins
for analog input, set PM20 to PM23 and PMC20 to PMC23 to 1. At this time, the output latches of P20 to P23
may be 0 or 1.
PM2 and PMC2 are set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PM2 to 00H and clears PMC2 to FFH.

Caution
If PMC20 to PMC23 are set to 1, the P20/ANI0/TI000/TOH1, P21/ANI1/TI010/TO00/INTP0,
P22/ANI2, and P23/ANI3 pins cannot be used for any purpose other than the A/D converter
function.
Be sure to set the pull-up resistor option registers (PU20 to PU23) to 0 for the pins set to
A/D converter mode.
