6.3 Memory Address Pointer
The Memory Address Pointer (MAP) byte comes after the address byte and selects the register to be read
or written. Refer to the pseudocode above for implementation details.
6.3.1 Map Auto Increment
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 regis-
ters.
7. REGISTER QUICK REFERENCE
This table shows the register and bit names with their associated default values.
EnDevCfg1 and EnDevCfg2 bits must be set to 1 for normal operation.
WARNING: All “Reserved” registers must maintain their default state to ensure proper functional operation.
