(5) Port input mode register 8 (PIM8)
(6) Port mode register 8 (PM8)
This register is used to enable or disable port 8 digital input in 1-bit units.
Set to digital input disable (used as analog input) to use a comparator or a programmable gain amplifier. Set to
digital input enable to use the port function or the external interrupt function, because digital input disable (used as
analog input) is set by default.
The PIM8 register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
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/INTP3/PGAI, P81/CMP0M, P82/CMP1P/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.
The PM80 to PM83 bits can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
Cautions 1. The port function that is alternatively used as the CMP0M, CMP1M pin can be used in the

comparator, and the internal reference voltage is used on the negative side. Using the output
mode, however, is prohibited.
