RHPM
Headphone mute for right channel, RHP output (active low).
0 = mute.
1 = unmute (default).
0
HPMODE
RHP and LHP output mode. These pins can be configured for either line outputs or headphone outputs. Logical
OR with the HPEN bit in Register R29. If either the HPMODE bit or the HPEN bit is set to 1, the headphone output
is enabled.
0 = enable line output (default).
1 = enable headphone output.
