Table 43 Controlling the “Beep” Path (IN3R to OUT2R)
Some example headphone output configurations are shown below.
A beep signal on the IN3R pin (see Table 43) can be mixed into OUT2R independently of the right
output mixer (i.e. without mixing the same beep signal into OUT1R).
Note that this feature is only possible when the inverting path configuration (MIXOUTR to OUT2R) is
selected. See Table 41 for the required register settings.
