Product Specification
19
• PC_HIOR (Input, 100K Pull-Up)
PCMCIA Mode: In PCMCIA I/O mode, this is the Input/Output Read
Strobe.
ATA/IDE Mode: Input/Output Read Strobe.
• PC_HIOW (Input, 100K Pull-Up)
PCMCIA Mode: In PCMCIA I/O mode, this is the Input/Output
Write Strobe.
ATA/IDE Mode: Input/Output Write Strobe.
• PC_HRESET/HRESET(Input, Schmitt-Triggered, 100K Pull-Up)
PCMCIA Mode: Active High input Reset signal.
ATA/IDE Mode: Active Low input Reset signal.
• PC_RDY/BSY/IREQ/HINT (Output, 8 mA)
PCMCIA Mode: In PCMCIA memory mode, this signal is READY/
BUSY. This signal will be asserted BUSY by the RESET logic. In
PCMCIA I/O mode, this signal is /IREQ.
ATA/IDE Mode: When enabled, the HINT signal is used to interrupt
the host (active High).
• PC_WP//IOIS16//IOCS16 (Output, Tri-State, 8 mA)
PCMCIA Mode: In PCMCIA memory mode, this signal is Write
Protected. In PCMCIA I/O mode, this signal is IOIS16 and indicates
that a 16-bit capable I/O device is being accessed on the PCMCIA
bus.
ATA/IDE Mode: I/O chip select 16 indicates that a 16- bit transfer is
active on the bus.
• PC_WAIT/IOCHRDY (Output, Tri-State, 8 mA)
PCMCIA Mode: Insert Wait States when held active and the chip is
being selected in I/O or memory mode.
ATA/IDE Mode: Inserts Wait States when held active, and when the
chip is being selected.
• PC_INPACK/DREQ (Output, Tri-State, 8 mA)
PCMCIA Mode: In PCMCIA I/O mode this signal is Input
Acknowledge. It is asserted by the card when the card is selected and
