INTR (Interrupt request output)
This signal is used to interrupt the CPU and its operation in the same as in mode 1. There
are two INTE flip-flops internally available for input and output to select either interrupt
of input or output operation. The INTE1 is used to control the interrupt request for output
operation and it can be reset by the bit set for PC6. INTE2 is used to control the interrupt
request for the input operation and it can be set by the bit set for PC4.
Mode 2 I/O Operation
Following is an example of the relation between the control word and the pin when used in
mode 2.
When input in mode 2 for group A and in mode 1 for group B.
