I/O KR0

KR1

KR2

This is a programmable 4-bit I/O port (PORT6).

√

Input and output in single-bit units can be specified.

When set for 4-bit units, an internal pull-up resistor

connection can be specified by software.

Notes 1. Circuit types enclosed in brackets indicate Schmitt trigger input.

2. VLC1 is selected as the input source for BP0 to BP7. The output level varies depending on the external circuit

for BP0 to BP7 and VLC1.

Example: As shown below, BP0 to BP7 are mutually connected via the µPD75P3018A, so the output levels of BP0 to BP7

are determined by the sizes of R1, R2, and R3.
