Z86017/Z16017 PCMCIA Interface Solution
Description
Enables Local Processor interrupt when PCMCIA host has
written CCR0, the Con•guration Option Register. This
interrupt stays present until this bit is set to 0. This bit is
active when set to 1. On Power-On Reset, this bit is set to
0. Also see Registers 06h, 2Ch.
Enables Local Processor interrupt when PCMCIA host has
written CCR1, the Card Status Register. This interrupt
stays present until this bit is set to 0. This bit is active when
set to 1. On Power-On Reset, this bit is set to 0. Also see
Registers 06h, 2Ch.
Enables Local Processor interrupt when PCMCIA host has
written CCR2, the Pin Replacement Register. This
interrupt stays present until this bit is set to 0. This bit is
active when set to 1. On Power-On Reset, this bit is set to
0. Also see Registers 06h, 2Ch.
Enables Local Processor interrupt when PCMCIA host has
written CCR3, the Socket and Copy Register. This
interrupt stays present until this bit is set to 0. This bit is
active when set to 1. On Power-On Reset, this bit is set to
0. Also see Registers 06h, 2Ch.
Enables Local Processor interrupt when ATA_IREQ is
asserted. This interrupt stays present until this bit is set to
0. This bit is active when set to 1. On Power-On Reset, this
bit is set to 0. Also see Registers 06h, 2Ch.
Enables external write protect pin as an input when set to
1. When set to 0, this bit is DASP on the local AT bus side.
On Power-On Reset, this bit is set to 0.
