5.4Port C Interrupt Enable Register (Base + 5)
INT7 - INT0 may be enabled by writing the appropriate bits in the Port C Interrupt Enable Register. The corresponding I/O channel must be configured as an input channel via the Data Port C Control Register if an interrupt is to be generated. If an I/O channel is configured as an interrupt source (INT7 - INT0), the I/O channel continues to be a standard data input channel (DATA23 - DATA16) and may be read just as any other input signal is read.
