Performance Monitoring Input.
When A0 through A2 are low, the LXT384 Transceiver is configured as an octal
line transceiver without monitoring.
When the LXT384 Transceiver is in Hardware mode, A3 is used in combination
with A2:0 for non-intrusive performance monitoring.
In non-multiplexed host processor mode, these pins function as processor
address pins.
