(6) Port mode register 8 (PM8)
This register is used to set port 8 input or output in 1-bit units.
Set the PM80 to PM83 bits to 1 to use the P80/CMP0P/TMOFF0/INTP3/PGAI, P81/CMP0M,
P82/CMP1P/TMOFF1/INTP7, or P83/CMP1M pin as the positive-side or negative-side input function of the
comparator, or the programmable gain amplifier input function.
The output latches of P80 to P83 may be 0 or 1 at this time.
PM80 to PM83 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.

in the input mode, when the CMP0P, CMP1P pin is selected as the positive-side input
of the comparator, and the internal reference voltage is used on the negative side.
Using the output mode, however, is prohibited.
The port function that is alternatively used as the CMP0M, CMP1M pin can be used
There is no P82/CMP1P/TMOFF1/INTP7 pin in the 78K0R/IB3.
