STATUS Register

3:2

Reserved

Reserved. Must be set to default value.

PLDRIVE0_PAD_

SHORT_VSS_

FAIL

When the flag is set, it indicates that the VSS check

during eye safety check failed for PLDRIVER0. The

PLDRIVER0 is disabled (no pulses are sent) in case of

failure but the proximity timing is maintained.

When ESIEN is 1, an interrupt is generated in the final

state after PROX_DATA_AVG is complete.

The flag is cleared when PON is made 0. Writing a 1 to

this field will clear the flag. To enable clear-by-read

function, INT_READ_CLEAR in the register CFG3 must be

set to 1.

PLDRIVER0_

PAD_SHORT_

VDD_FAIL

PLDRIVER0 is disabled (no pulses are sent) in case of

failure but the proximity timing is maintained.

state after PROX_DATA_AVG is complete.

The flag is cleared when PON is made 0. Writing a 1 to

this field will clear the flag. To enable clear-by-read

Bit Description

PINT_GRT_HTH

R, SC

Proximity interrupt is due to PDATA exceeds the high

threshold (PIHT). Clearing PINT flag will clear this flag

as well.

PINT_LES_LTH

R, SC

Proximity interrupt is due to PDATA exceeds the low

threshold (PILT). Clearing PINT flag will clear this flag

as well.

PSAT

RW, SC

Proximity saturation flag indicates that a PSAT_2STG

or AMBCOMP_LVL_SAT or PSAT_1STG_PULSE or

PSAT_1STG_AMB event occurred during a previous

proximity cycle.

4PINT

RW, SC

Proximity interrupt flag indicates that proximity

results have exceeded thresholds and persistence

settings.

3CINT

RW, SC

Calibration interrupt flag indicates that calibration

has completed.
