Description
0 - 15
Port Enable
. When set to 1, the corresponding input and output ports are enabled and packets can be received
and transmitted after DASL synchronization. When set to 0, the port is disabled and no packet transits on that
port.
Bit n of the register corresponds to port n.
If any packets are enqueued for a disabled output, they are flushed.
The DASL lines of a port that is disabled are tri-stated.
When the port is disabled the M3 doesn’t perform dynamic phase alignment for temperature.
