Bits 3-0: IRQ Level
These bits determine which IRQ will occur when the card causes an interrupt through the RDY/
-IREQ pin on the PCMCIA socket.
Bit 4: Manage Int Enable
This bit was created to determine how management interrupts occur on ISA-based systems. It is
included for software compatibility. Because there is no -INTR pin on the PCI bus, setting this bit
to a ‘1’ would cause management interrupts not to occur.
Bit 5: Card Is I/O
This bit determines how dual-function socket interface pins will be used. For more information on

Reserved. No hardware function in the PD6729.
Sets Memory Card Interface mode. The card socket is configured to support memory-only-type
cards. All dual-function socket interface pins are defined to perform memory-only-type interface
functions.
Sets I/O Card Interface mode. The card socket is configured to support combined I/O-and-
memory-type cards. All dual-function socket interface pins are defined to perform all I/O and
basic memory type interface functions.
