Once an operation has been performed on the Processor port the
address index is available here. Useful as an index for associated
tables in software.
SWEX flag
PWEX flag
LQUEUE flag
AQUEUE flag
Processor Port Match flag; 1 = Match
Full flag; 1 = Full
Indicates the LQUEUE has at least one entry. Note this bit is available
even if the INT pin is disabled. A read clears the interrupt.
Indicates the AQUEUE has at least one entry. Note this bit is available
even if the INT pin is disabled. A read clears the interrupt.
Indicates a write exception condition has occurred on the processor
port. A read clears the interrupt.
Indicates a write exception condition has occurred on the syncport. A
read clears the interrupt.
When auto-aging is enabled the CLK is divided by the value in this reg-
ister to provide the auto-age interval. Resets to 02FAF080h = 1 second
with 50 MHz CLK.
This register sets the life of a learned entry in units of the auto-age
Interval register. Resets to 012Ch = 300.
