Bit Bit description

[7] DMUX: digital multiplexer output

0: FS flag selected

1: OC flag selected. In case the OCFT_DIS bit in Control Register 8 is "1", then the DOUT pin

reflects directly the overcurrent comparator output and the CSAOC bit in Status Register 6 is not

set if an overcurrent event occurs.

[6:4] AMUX: analog multiplexer output

000: OFF

001: 1/8 VS

010: 1/8 VSREG

011: 1/8

VSMS

100: TJ

101: CSA reference voltage

110: CSA reference voltage is muxed to AOUT and CSO pins at the same time

111: not used

[3] WOBM: charge pump frequency modulation

0: frequency modulation enabled

1: frequency modulation disabled

[2] WOBF: charge pump modulation frequency

0: 16 kHz

1: 32 kHz

[1] Reserved, keep default value [0]

[0] Reserved
