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.
4. A 12X is a NC for IDT70P248, therefore Interrrupt Addresses are FFF and FFE.

NOTES:
5675 tbl 16
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
IDT70P258/248 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.
