NOTES:  
1. Pins BUSYL and BUSYR are both outputs on the IDT7133 (MASTER). Both are  
inputs on the IDT7143 (SLAVE). 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. H” 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  
= VIL will result BUSYL and BUSYR outputs can not 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.
