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
X
outputs on the
IDT70V16/5 are push-pull, not open drain outputs. On slaves the
BUSY
X
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. "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
= LOW will result.
BUSY
L
and
BUSY
R
outputs can not 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.
4. A

1. This table denotes a sequence of events for only one of the eight semaphores on the IDT70V16/5.
2. There are eight semaphore flags written to via I/O
