NOTES:
1. Assumes BUSY L = BUSY R = V IH .
2. If BUSY L = V IL , then no change.
3. If BUSY R = V IL , then no change.

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 IDT70V05 are push
pull, not open drain outputs. On slaves the BUSY X input internally inhibits writes.
2. V IL 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.

1. This table denotes a sequence of events for only one of the eight semaphores on the IDT70V05.
2. There are eight semaphore flags written to via I/O 0 and read from all I/O's (I/O 0 -I/O 7 ). These eight semaphores are addressed by A 0 -A 2 .
3. CE = V IH , SEM = V IL to access the semaphores. Refer to the Semaphore Read/Write Control Truth Table.
