KR0
This is a programmable 4-bit I/O port (PORT6).
Input and output can be specified in bit units.
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.

Notes 1.
Circuit types enclosed in brackets indicate Schmitt trigger input.
2.
BP0 through BP7 select V
LC1
as an input source.
However, the output levels change depending on the external circuit of BP0 through BP7 and V
LC1
.
Example
Because BP0 through BP7 are mutually connected inside the
m
PD75P3036, the output levels of BP0 through
BP7 are determined by R

, R

, and R
3
.
