Bit 3

NODATA: No data in buffer (valid

also for two level STD sensors but

in this case, where data bits are not

expected, this bit is high during

normal communication)

0 => no fault

1 => fault

SSM_RESET

LBIST

Bit 2

PULSE OVERFLOW: Pulse

duration counter overflow

(available only for PWM encoded

WSS)

0 => no fault

1 => fault

SSM_RESET

Bit 19:10

the content of this register is value

of first delta (∆Ith1)

LSB=93.75 µA typ.

0x4B

SSM_RESET

LBIST

Bit 9:0:

In case WSS_READ_CURRENT

bit = 0 the content of this register is

value of base current (IB0); in case

WSS_READ_CURRENT bit = 1 the

content of the register is value of

instantaneous current in RSULx

pin.

In both cases LSB=93.75 µA typ.
