Address 0001h.
The block programming register stores the bit patterns to be loaded into the connection memories when the
Memory Block Programming feature is enabled. The BPE, LBPD2-0 and BBPD2-0 bits in the BPR register must
be defined in the same write operation.
The BPE bit is set HIGH, to commence the block programming operation. Programming is completed in one frame
period and may be be instigated at any time within a frame.The BPE bit returns to LOW to indicate the block
programming function has completed.
