7.5. I/O Port

There are 12 IOs (IOC3-0 and IOD7-0) in the GPCL A1/B1 series;

IOC3-0 is a nibble-controlled IO, but IOD7-0 is a bit-controlled IO.

They can be programmed as input (pure input or pull-low) or

output buffer.

A pull-low input IOD7-0 keeps a less impedance to

get better noise immunity.

While pressing the key (IOD7-0 to

VDD), a larger impedance is retained to save DC power.

IOD6

can be programmed as an external interrupt source.

IOD7 can

be programmed as an IR transmitter.
