The BPR is only accessible when the device is in the Enhanced mode. There is one BPR for each block in the device. For each
Priority in the BPR, there is an alias address (Block Priority Register Address) which allows individual priorities to be updated.
Table 5-17 shows the BPR fields.

Soft Priority #3. There are four Priority fields in each BPR. Each Priority represents the
priority of a sub-block located within the block associated with this register. Priority value
of 00 (hex) is highest and FF (hex) is lowest in priority.
The addresses in a block associated with each Soft Priority is as follows:
Entry Index 0 to 511: Priority0
Entry Index 512-1023: Priority1
Entry Index 1024-1535: Priority2
Entry Index 1536-2047: Priority3
Soft Priority #2. See Soft Priority #3 description.
Soft Priority #1. See Soft Priority #3 description.
Soft Priority #0. See Soft Priority #3 description.
Reserved.
V #3. There are four V fields in each BPR. Each field represent the valid bit for a sub-block
within the block associated with this register. If this bit is set to 1 and the Soft Priority in
the CPR selected by the operation matches, the associated sub-block will participate in
the operation. If this bit is set to 0, the associated sub-block will not participate in a Search
operation.
V #2. See V #3 description.
V #1. See V #3 description.
V #0. See V #3 description.
