Description

OUTCONVH

16(2)

Time reference, result of conversion time

measurement (most significant byte and

one empty byte with 00h).

Read access of address 0h in measurement state results in a first byte for OSR information and a second byte for

STATUS information.

(2)

The Least Significant Byte comes first.

Bit Description

OUTCONVOF(1)(2)

Digital overflow of the internal 24-

bit time reference OUTCONV.

MRESOF(2)

Overflow of at least one of the

measurement result registers

MRES1 … MRES3.

ADCOF(2)

Overflow of at least one of the

internal conversion channels

during the measurement (e.g.

caused by pulsed light)

– analog

evaluation is made.

LDATA(3)

Measurement results in the buffer

registers were overwritten before

they were transferred to the output

result registers. A transfer takes

place as part of an I²C read

process of at least one register of

the output register bank.

NDATA(4)

New measurement results were

transferred from the temporary

storage to the output result

registers.
