HLSI

HIGH/LOW Side Injection: if HLSI = 1 then HIGH side LO injection; if HLSI = 0 then
LOW side LO injection

Mono to Stereo: if MS = 1 then forced mono; if MS = 0 then stereo ON

Mute Right: if MR = 1 then the right audio channel is muted and forced mono; if MR = 0
then the right audio channel is not muted

Mute Left: if ML = 1 then the left audio channel is muted and forced mono; if ML = 0
then the left audio channel is not muted

SWP1

Software programmable port 1: if SWP1 = 1 then port 1 is HIGH; if SWP1 = 0 then
port 1 is LOW
