Description
System reset input:
When this pin is set to the "L" level, the internal
status is initialized to start execution of
instructions from address 0040H. The input is
pulled up to VDD with an internal pull-up resistor.
8-bit input-output port (port 0):
Each of bits 0 to 7 is configured to be input or
output by use of 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. See Secondary function.
8-bit input-output port (port 1):
Each of bits 0 to 7 is configured to be input or
output by use of 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. See Secondary function.
8-bit input-output port (port 2):
Each of bits 0 to 7 is configured to be input or
output by use of the direction register of port 2
(P2DIR). In addition to the basic function as the
input-output port, a secondary function is allocated
to each of P2.0 through P2.3. See Secondary function.
