Description

Bit 0 (LSB)

TDET

22 kHz tone presence is detected on the DETIN pin

No 22 kHz tone is detected on the DETIN pin

Bit 1

N/A

Reserved

Bit 2

TMON

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

specification threshold: the tone frequency or the ATONE

(tone amplitude) is out of the thresholds guaranteed in the

TMON electrical characteristics

22 kHz tone present on the DETIN pin is within TMON

specification thresholds. Refer to Table 19: "22 kHz tone

diagnostic (TMON bit, status 2 register) characteristics"

Bit 3

Bit 4

IMON

Output current (from VOUT pin) is lower than IMON

specification thresholds

Output current (from VOUT pin) is higher than IMON

specifications
