BM Ready
When set, indicates the Buffer Manager tables have finished being initialized
by the reset process. The initialization is performed upon any reset that
resets the switch fabric.
Buffer Manager Reset Status Register (BM_RST_STS)
This register indicates when the Buffer Manager has been initialized by the reset process.
Note 14.63 The default value of this bit is 0 immediately following any switch fabric reset and then self-
Register #:
sets to 1 once the ALR table is initialized.
