Description
PPI D Interrupt Request for Port B—If this bit and the INTEN bit
in Interrupt Control Register 2 are both set, PPI D sends an
interrupt, INTRB, to the host computer. If this bit is cleared, PPI D
does not send the interrupt INTRB to the host computer, regardless
of the setting of INTEN.
PPI D Interrupt Request for Port A—If this bit and the INTEN bit
in Interrupt Control Register 2 are both set, PPI D sends an
interrupt, INTRA, to the host computer. If this bit is cleared,
PPI D does not send the interrupt INTRA to the host computer,
regardless of the setting of INTEN.
PPI C Interrupt Request for Port B—If this bit and the INTEN bit
in Interrupt Control Register 2 are both set, PPI C sends an
interrupt, INTRB, to the host computer. If this bit is cleared, PPI C
does not send the interrupt INTRB to the host computer, regardless
of the setting of INTEN.
PPI C Interrupt Request for Port A—If this bit and the INTEN bit
in Interrupt Control Register 2 are both set, PPI C sends an
interrupt, INTRA, to the host computer. If this bit is cleared, PPI C
does not send the interrupt INTRA to the host computer, regardless
of the setting of INTEN.
PPI B Interrupt Request for Port B—If this bit and the INTEN bit
in Interrupt Control Register 2 are both set, PPI B sends an
interrupt, INTRB, to the host computer. If this bit is cleared, PPI B
does not send the interrupt INTRB to the host computer, regardless
of the setting of INTEN.
