SDHC: Short Protection Disable for HPC (Headphone COM/Monaural Output)
SDHR: Short Protection Disable for HPR (R-Channel Headphone)
SDHL: Short Protection Disable for HPL (L-Channel Headphone)
Default value: 0
Short-circuit protection can be disabled if this function is not needed in an application.
SDHC, SDHR, SDHL = 0
SDHC, SDHR, SDHL = 1
Enabled (default)
Disabled
SDSR: Thermal Protection Disable for SPR (Speaker Amplifier R-Channel)
SDSL: Thermal Protection Disable for SPL (Speaker Amplifier L-Channel)
Default value: 0
The thermal protection circuit can be disabled if this function is not needed in an application.

RLSR: Reset Thermal Protection Circuit for SPR (R-Channel Speaker Amplifier)
RLSL: Reset Thermal Protection Circuit for SPL (L-Channel Speaker Amplifier)
Default value: 0
A thermal protection circuit puts the device in power-down status after it detects a temperature of approximately
150
°
C on the die. These bits must be set to 1 to restore power to the speaker amplifier.
RLSR, RLSL = 0
RLSR, RLSL = 1
Operation (default)
Reset (set to 0 automatically after being set to 1)
