These bits specify the number of Flash blocks to include in an automatic CRC cal-
culation. The last address of the last Flash block included in the automatic CRC
calculation is (CRC0ST+CRC0CNT) x Block Size - 1.

1. The block size is 256 bytes.
2. The maximum number of blocks that may be computed in a single operation is 31.
To compute a CRC on all 32 blocks, perform one operation on 31 blocks, then
perform a second operation on 1 block without clearing the CRC result.
