BUSY
NOTES:
1. Pins
BUSY
L
and
BUSY
R
are both outputs when the part is configured as a master. Both are inputs when configured as a slave.
BUSY
outputs on the IDT70V24 are push
pull, not open drain outputs. On slaves the
BUSY
input internally inhibits writes.
2. L if the inputs to the opposite port were stable prior to the address and enable inputs of this port. V
IH
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
= LOW will result.
BUSY
L
and
BUSY
R
outputs cannot be LOW simultaneously.
3. 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.

NOTES:
1. This table denotes a sequence of events for only one of the eight semaphores on the IDT70V24.
2. There are eight semaphore flags written to via I/O
0
and read fromall I/O's (I/O
