8.6 Register Maps
8.6.1 Register Initialization
After power up (VDD supplied, ENABLE Pin low to high transition) the internal registers are initialized with the
default value. Disabling the part by pulling ENABLE pin to GND will set the device into total shutdown. As the
internal LDO is turned off settings in the register will be lost. The device initializes the registers with default
values with the next enable (ENABLE pin to VDD).
