Send start condition.
Send 10010100 (chip address & write operation).
Receive acknowledge bit.

Send start condition.
Send 10010101 (chip address & read operation).
Receive acknowledge bit.
Receive byte, contents of selected register.
Send acknowledge bit.
Send stop condition.
Setting the auto-increment bit in the MAP allows successive reads or writes of consecutive registers. Each
byte is separated by an acknowledge bit.
5.1.1
Memory Address Pointer (MAP)
The MAP byte comes after the address byte and selects the register to be read or written. Refer to the
pseudo code above for implementation details.
5.1.1.1
Map Increment (INCR)
The device has MAP auto-increment capability enabled by the INCR bit (the MSB) of the MAP. If INCR is
set to 0, MAP will stay constant for successive IC writes or reads. If INCR is set to 1, MAP will auto-in-
crement after each byte is read or written, allowing block reads or writes of successive registers.
