Input/output Ports
The microcomputer has a total of 96 input/output ports P0-
P22. (However, P5 is reserved for future use, P14, P16, and
P18-P21 do not exist. ) The input/output ports can be used
as input ports or output ports by setting uptheir direction reg-
isters.
Each input/output port is a dual-function pin shared with
otherinternal peripheral I/O or external extended bus signal
lines.These pin functions are selected by using the chip op-
eration mode select or the input/output port operation mode
registers.

Port function
The input/output ports can be set for input or output mode bitwise by using the input/output port direction
control register. (However, P221 is CAN input-only port. )
Pin function
Dual-functions shared with peripheral I/O or external extended signals (or multi-functions shared with periph
eral I/Os which have multiple functions. )
Pin function
P0-P4: Changed by setting CPU operation mode (MOD0 and MOD1 pins)
changeover
P6-22: Changed by setting the input/output port operation mode register.
(However, peripheral I/O pin functions are selected using the peripheral I/O register. )
Note: Input/output ports P14, P16, and P18-P21 do not exist.
