NOTES:  
1. Assumes BUSYL = BUSYR = VIH.  
2. If BUSYL = VIL, then no change.  
3. If BUSYR = VIL, then no change.  
4. A12X is a NC for IDT70P246, therefore Interrrupt Addresses are FFF and FFE.

NOTES:  
1. Pins BUSYL and BUSYR are both outputs when the part is configured as a master. Both are inputs when configured as a slave. BUSY outputs on the  
IDT70P256/246 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. VIH if the inputs to the opposite port became stable after the address  
and enable inputs of this port. If tAPS is not met, either BUSYL or BUSYR = LOW will result. BUSYL and BUSYR outputs cannot be LOW simultaneously.  
3. Writes to the left port are internally ignored when BUSYL outputs are driving LOW regardless of actual logic level on the pin. Writes to the right port are internally ignored when  
BUSYR outputs are driving LOW regardless of actual logic level on the pin.
