.
If AutoInc = 1, then the address register will be incremented automatically and subsequent data bytes can be read
from successive registers, without providing a second RAB
When the auto-increment mode is enabled (AutoInc is set to 1), the Address Register will continue incrementing for
each read cycle. When the content of the Address Register reaches 2A, it will wrap around and start from 00h again.
The auto increment sequence can be terminated by either a “STOP” or “RESTART” condition. The read operation
can be terminated with a “STOP” condition.
