Field

Description

SDCD_EN

SDCD function

0 (default after a POR or soft reset event when BT_MODE = GND): SDCD function is disabled. All

clocks and power for the function are turned off.

1 (default after a POR or soft reset event when BT_MODE = VDD and MOT_DET = 1): SDCD function

is enabled. When this bit is set, the 12-bit reference values (

REF_X/Y/Z) are initialized per the

settings made in REF_UPDM[1:0].
