BUSY
NOTES:
1.
Pins
BUSY
L
and
BUSY
R
are both outputs on the IDT7133 (MASTER). Both are
inputs on the IDT7143 (SLAVE). On Slaves the
BUSY
input internally inhibits
writes.
"L" if the inputs to the opposite port were stable prior to the address and enable
inputs of this port.
“
H
”
if the inputs to the opposite port became stable after the
address and enable inputs of this port. If t
APS
is not met, either
BUSY
L
or
BUSY
R
= V
IL
will result
BUSY
L
and
BUSY
R
outputs can not be LOW simultaneously.
Writes to the left port are internally ignored when
BUSY
L
outputs are driving LOW
regardless of actual logic level on the pin. Writes to the right port are internally
ignored when
BUSY
R
outputs are driving LOW regardless of actual logic level on
the pin.
