Port 0
4-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, an on-chip pull-up resistor can be used by
software.
Port 1
8-bit input only port.
Port 2
6-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, an on-chip pull-up resistor can be used by
software.
Port 3
7-bit input/output port.
Input/output can be specified
bit-wise.
N-ch open-drain input/output port.
LEDs can be driven directly.
When used as an input port, an on-chip pull-
up resistor can be used by software.
Port 4
8-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, an on-chip pull-up resistor can be used by
software.
Test input flag (KRIF) is set to 1 by the falling-edge detection.
Port 5
8-bit input/output port.
LEDs can be driven directly.
Input/output can be specified bit-wise.
When used as an input port, an on-chip pull-up resistor can be used by
software.
