R Line level inputs (LINL, LINR).
Microphone level inputs (MINL, MINR).
R When read as 1, this bit indicates that an input over-
range condition has occurred. The bit remains set
until cleared by writing 0 into the register. Writing
a 1 enables the overrange detection. The bit will
remain 0 until an over-range occurs. Serial port
clear has priority over internal settings.
R Parallel input/output bits.
