NREG
I
Attribute Memory Select - Driven by the host to select between Attribute mem-
ory or I/O space (REG asserted) and Common memory (REG deasserted) in
the device and the PCMCIA card.
Extend Bus Cycle - This signal is asserted by the device to delay completion of
the access cycle currently in progress.
Input Acknowledge - It is asserted when the BT device is selected and can
respond to an I/O read cycle at the address currently apllied on the address
bus. It is used by the host to control the enabe of any input buffer between the
card and the CPU. It will be inactive during card configuration.
Interrupt Request - Asserted by the chip to indicate to the host that software
service should take place.
