4.3.1
Port 0
Port 0 is a 5-bit port for which I/O settings can be controlled in 1-bit units.
Port 0 includes the following alternate-function pins.

Note
The DRST pin is for on-chip debugging (flash memory version only).
If on-chip debugging is not used, fix the P05/INTP2/DRST pin to low level between when the reset signal of
the RESET pin is released and when the OCDM.OCDM0 bit is cleared (0). Although the mask ROM
versions do not support the on-chip debug mode, an on-chip pull-down resistor is incorporated. Handle the
P05/INTP2 pin the same as in flash memory versions.
For details, see 4.6.3 Cautions on on-chip debug pins.
Caution
The P02 to P06 pins have hysteresis characteristics in the input mode of the alternate function,
but do not have hysteresis characteristics in the port mode.
