Address:
MASS — Mass Erase Control Bit
ERASE — Erase Control Bit
PGM — Program Control Bit
DOT[15:8] — OSD FLASH Even High Byte Buffer
These bits define the byte to be programmed to an even address
location of the 13K-bytes array. The contents of this register will be
automatically programmed to the even address ($xxxx) location when
the odd address ($xxxx+1) is programmed. Reset has no effect on these
bits. See
map.

Write:
This read/write bit configures the memory for erase operation. ERASE
is interlocked with the PGM bit such that both bits cannot be equal to
1 or set to 1 at the same time.
This read/write bit configures the memory for mass erase operation or
block erase operation when the ERASE bit is set.
This read/write bit configures the memory for program operation.
PGM is interlocked with the ERASE bit such that both bits cannot be
equal to 1 or set to 1 at the same time.
1 = Mass Erase operation selected
0 = Mass Erase operation not selected
1 = Erase operation selected
0 = Erase operation not selected
1 = Program operation selected
0 = Program operation not selected
