Bits labeled "Reserved" are reserved for future enhancements. They may not be written to. When read, they will
show a "0" value.
Bits labeled "RFT" are reserved for TI testing. Under no circumstances must any data be written to these
registers. Writing to these bits may change the function of the device, or cause complete failure. If read, these
bits may assume any value.

HP_EN_L
Enable bit for the left-channel amplifier. Amplifier is active when bit is high.
HP_EN_R
Enable bit for the right-channel amplifier. Amplifier is active when bit is high.
Mode[1:0]
Mode bits Mode[1] and Mode[0] select one of three modes of operation. 00 is stereo headphone
mode. 01 is dual mono headphone mode. 10 is bridge-tied load mode.
Reserved
These bits are reserved for future enhancements. They may not be written to. When read they will
read as zero.
Thermal
A 1 on this bit indicates a thermal shutdown was initiated by the hardware. When the temperature
drops to safe levels, the device will start to operate again, regardless of bit status. This bit is
clear-on-read.
SWS
Software shutdown control. When the bit is one, the device is in software shutdown. When the bit
is low, the charge-pump is active. SWS must be low for normal operation.
