POWER-ON
Input/Output Each terminal can be used to input or output 1 bit at a time. The output section has a latch which
holds 1 bit. One of the D ports is assigned by register Y as a data point, to execute input or output.
To use the port for input, set the output latch for that bit to "1". All of the output latches on port D can
be set to "1" using the CLD command.
