computer. If this bit is cleared, PPI D does not send
the interrupt INTRA to the computer, regardless of
the setting of INTEN.
5 CIRQ1 PPI C Port B Interrupt Enable Bit—If this bit and the
INTEN bit in Interrupt Control Register 2 are both
set, PPI C sends an interrupt, INTRB, to the
computer. If this bit is cleared, PPI C does not send
the interrupt INTRB to the computer, regardless of
the setting of INTEN.
4 CIRQ0 PPI C Port A Interrupt Enable Bit—If this bit and the
