Default Value: 00000000h
Access:

This register is used to enable a scheduler port to carry traffic. After reset this register is 0 - all scheduler
ports are disabled. While a scheduler port is disabled it will not respond to requests from the attached port
card, nor will it issue grants.
Bits
Description
31:0
Enable Port. Each bit indicates if the corresponding port should be enabled.
NOTE: Reading this register only reflects the last value written to it. A CRC error, for example,
might cause a Scheduler port to become inactive, but that change will not be reflected in
this register. Similarly, if a port is active, then setting the port to inactive by writing to the
Reset Port register will not be reflected in this register even though the port will be
inactive. Whenever a port is reset the appropriate bit in this register should also be
cleared.
