Description
Bit 0
(LSB)
TDET
1
22 kHz tone presence is detected on the DETIN pin
0
No 22 kHz tone is detected on the DETIN pin
Bit 1
N/A
-
Reserved
Bit 2
TMON
1
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 the TMON electrical characteristics table.
0
22 kHz tone present on the DETIN pin is within TMON specification thresholds.
Refer to
Table 19.
Bit 3

Reserved
Bit 4
IMON
1
Output current (from VOUT pin) is lower than IMON specification thresholds. Refer
to
Table 18.
0
Output current (from VOUT pin) is higher than IMON specifications. Refer
to
Table 18.
