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.
When A2:0 are all ‘0’, there is no performance monitoring of receivers, and
the LXT384 Transceiver is configured as an octal line transceiver without
monitoring capability.
When A2:0 are not all ‘0’ and:
When A3 = ‘0’, performance monitoring of receivers occurs as shown in
the following table.
When A3 = ‘1’, performance monitoring of transmitters occurs as shown in
the following table. (Transmitter monitoring is not supported when the
respective channel is set to analog loopback mode.)
In non-multiplexed host processor mode, these pins function as processor
address pins.
