For the NND_ACCESS/NND_FIFO register (program operation):
Other combinations of MBYTEEN are not permitted.
For all other registers:
The BE bit has no effect on other NFC registers. Only MBYTEEN bits apply.

Bit 4: For the current NFMCs, bit 8 of the address is not sent to NFMC, because
its functionality is replaced by a pointer set by command 0x00, 0x01, or 0x50.
