CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Input Ports)
Input comparison
registers and inter-
rupt function
The interrupt mask registers (EIK00–EIK03) enable the
interrupt mask to be selected individually for K00–K03. An
interrupt occurs when the input value which are not
masked change and the interrupt factor flag (IK0) is set to
"1".

Input interrupt circuit
configuration (K00–K03)
All four input port bits (K00–K03) provide the interrupt
function. The conditions for issuing an interrupt can be set
by the software for the four bits. Also, whether to mask the
interrupt function can be selected individually for all four
bits by the software. Figure 4.3.2 shows the configuration of
K00–K03.
