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.

4.9.3.1 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 I²C writes or reads and SPI writes. If INCR is set to 1, MAP

will auto-increment after each byte is read or written, allowing block reads or writes of successive registers.
