In PS/2 mode, this input indicates whether a
second drive is connected; DRV2 should be
low if a second drive is connected. This status
is reflected in a read of Status Register A.
Active low address decode out: used to
decode a 1, 8, or 16 byte address block. (An

Configuration registers CR03, CR08 and
CR09 for more information. This pin has a
30ua internal pull-up. The interrupt request
from a logical device or IRQIN may be output
on IRQ_B. Refer to the configuration registers
for more information.
(If EPP or ECP Mode is enabled, this output is
pulsed low, then released to allow sharing of
interrupts.)
This pin is used to steer an interrupt signal
from an external device onto one of eight IRQ
outputs IRQA-H.
This active high input indicates that the power

must be active. When PWRGD is inactive, all
inputs to Mercury are disconnected and put
into a low power mode; all outputs are put into
high impedance. The contents of all registers
are preserved as long as V
value. The driver current drain in this mode
drops to ISTBY - standby current. This input
has an internal 30ua pull-up.
