Block Priority Register Aliases (BPRA)
The BPRA is only accessible when the device is in the Enhanced mode. There are four BPRAs for each block. These pseudo
registers provide an alternate means to update the associated block’s BPR. The fields of these BPRAs exactly match the BPR
fields. Please see the corresponding BPR fields for the descriptions of the BPRAs fields.
Table 5-20 shows the BPRA fields for BPR’s Priority0.
