present on the same board and a single nCS line is used.
1
WORD ADDRESS 1
0
This is the LSB of the two bits used to address the word.
2
WORD ADDRESS 2
0
This is the MSB of the two bits used to address the word.
3
NSLEEP
0
This bit is used to decide if the device should exit sleep mode.
4
OFF1
0
LSB for fixing the Toff time (see following Table 32).
5
OFF2
