s
trobe. Input. Active High. Mode 2.
When the IA82527 is configured to operate in either the 8-bit
multiplexed non-Intel
architecture mode (Mode 2), this signal latches
the address into the device during the address phase of the bus
cycle.
NOTE
: If the IA82527 is configured to operate in Mode 3 (8-bit non-
multiplexed non-Intel
architecture), this pin must be tied high.
cl

out
. Output (push-pull).
This output provides a programmable clock frequency. The
frequency is set via the Clockout Register (1FH) and can range from
the frequency of the
xtal
(crystal) input to xtal/
n
, where
n
can be an
integer value from 2 through 15. This output allows the IA82527 to
clock other devices such as the host CPU.

hase. Input. Serial Interface Mode.
When this input is a logic 0, data are sampled on the rising edge of
sclk
. When this input is a logic 1, data are sampled on the falling
edge of
sclk
.

elect. Input. Active Low (Modes 0–3); Selectable Active Level
(Serial Interface Mode).
When the IA82527 is configured to operate in one of the parallel
interface modes (Modes 0–3) or the Serial Interface Mode, this input,
during its active state, selects the device allowing CPU access.
For Serial Interface Mode operation, the active state is selectable
(i.e., either high or low) via the IA8257
csas
pin.

When this input is a logic 0, the

input is configured to function
active low. When this input is a logic 1, the
cs_n
input is configured
to function active high.
