100 1101b (4Dh): Register 77
HPDS: Headphone Detection Status
Default value: 0
The HPDS bit shows the status of insertion detection for the headphone. This is a read-only bit. The polarity
depends on the register 75 (HPDP) setting.
HPDS = 0
HPDS = 1
HDTI input (when HPDP = 0) (default)
Inverted HDTI input (When HPDP = 1)
STHC: Short Protection Status for HPC (Headphone COM/Monaural Output)
STHR: Short Protection Status for HPR (R-Channel Headphone)
STHL: Short Protection Status for HPL (L-Channel Headphone)
These bits can be used to read short protection status through the I
2
C interface.
STHC, STHR, STHL = 0
STHC, STHR, STHL = 1
Detect short circuit
Not detect short circuit
STSR: Thermal Protection Status for SPR (R-Channel Speaker)
STSL: Thermal Protection Status for SPL (L-Channel Speaker)
These bits can be used to read thermal protection status through the I
2
C interface.
STSR, STSL = 0
STSR, STSL = 1
Detect thermal protection
Not detect thermal protection
