Description
8-bit Input-output port (port 0):
Each of bits 0 to 7 is configured to be an input or
an output by the direction register of port 0
(P0DIR).
In addition to the basic function as the Input-output
port, a secondary function is allocated to each of
P0.0 through P0.7. Refer to the next table.
8-bit Input-output port (port 1):
Each of bits 0 to 7 is configured to be input or
output by the direction register of port 1 (P1DIR).
In addition to the basic function as the Input-output
port, a secondary function is allocated to each of
P1.0 through P1.7. Refer to the next table.
Input port (port 2.0)
Output port (port 2.1)
Pulled high at the time of reset. If this pin is set to
the "0" level during reset, this IC goes into a test
mode, disabling execution of the user program.
Input-output port (port 2.2)
8-bit input port (port 3):
Each of P3.0 to P3.7 functions as analog input
channel of A/D converter.
4-bit output port:
These pins are valid only for the MSM65352.

In the case of MSM65352B, SEG0 to SEG19 and
Pin 33 to Pin 52 are used.
