and A2.
Output port is arranged to P72 to P75,
P80 and P81.

Read port P1
By setting to register, the state of port
register can be read always.
The state of port when input mode.
The state of port register when output
mode.
P44/CS0 - P47/CS3
If a Vcc level is applied to the CNVss
pin, bit 2 (PU11) of pull-up control
register 1 turns to "1" when reset, and
P44/ CS0 - P47/ CS3 turn involved in
pull-up.
Bit 2 (PU11) of the pull-up control
register 1 turns to "0" when reset, and
P44/ CS0 - P47/ CS3 turn free from pull-
up.

Note 1: M16C/61T group, and M16C/62T group are not guaranteed operating of memory expansion, but it is
mentioned in the table for clear the difference of capacity.
Note 2: In 80-pin package(M30613, M30623), pins of a part are not connected to the external pin, so do not
use these functions and pins.
