Description

Bit 0

(LSB)

TDET-A

22 kHz tone presence is detected on the DETIN pin

No 22 kHz tone is detected on the DETIN pin

Bit 1

TDET-B

22 kHz tone presence is detected on the DETIN pin

No 22 kHz tone is detected on the DETIN pin

Bit 2

TMON-A

22 kHz tone present on the DETIN pin is out of TMON specification thresholds.

That is: the tone frequency or the ATONE (tone amplitude) are out of the

thresholds guaranteed in

Table 19.

22 kHz tone present on the DETIN pin is within TMON specification

thresholds. Refer to

Table 19.

Bit 3

TMON-B

22 kHz tone present on the DETIN pin is out of TMON specification thresholds.

That is: the tone frequency or the ATONE (tone amplitude) are out of the

thresholds guaranteed in

Table 19.

22 kHz tone present on DETIN pin is within TMON specification thresholds.

Refer to

Table 19.

Bit 4

IMON-A

Output current (from VOUT pin) is lower than IMON specification thresholds.

Refer to

Table 18.

Output current (from VOUT pin) is higher than IMON specifications.

Refer to

Table 18.

Bit 5

IMON-B

Output current (from VOUT pin) is lower than IMON specification thresholds.

Refer to

Table 18.

Output current (from VOUT pin) is higher than IMON specifications.

Refer to

Table 18.
