Table 82. Master Queue 0 (MQ0) (015Ch)
Name
Bit Pos. Type Reset
Description
mast_queue_in[31:16] 15:0 RW
0 Master Queue Indication [31:16]. Each bit in this field rep-
resents one of 16 queues from the 64 queues in the T8207
device, where the least significant bit is queue 16 and most
significant bit is queue 31. These bits indicate which queues
in the device are enabled for shared UTOPIA mode. If the
associated bit is ‘1,’ it indicates that the queue is enabled.
These bits must be programmed in both the master and
slave devices.
Note: These bits must be programmed even when the
device is not used in shared UTOPIA mode.
Note: Shared UTOPIA mode supports up to 32 queues only.
