9.2.1
SUBADDRESS
If more than 1 data byte is transmitted, then auto-increment is performed: starting from the transmitted subaddress and
auto-increment of subaddress in accordance with the order of Table 10.
Table 10 Denition of the subaddress (second byte after slave address); note 1
Notes
1. X = don’t care.
2. Bit A7 = 1 is not allowed.
3. Bits A6 to A2 will be ignored by the internal hardware.
