REF6-0: Set the Reference value at Auto Recovery Operation
During the auto recovery operation, when IPGA value becomes the reference value set by
REF6-0, the gain of the auto recovery operation does not exceed the reference value. The
reference value is set commonly as for Lch and Rch.
During the auto recovery operation, if IPGA value exceeds the setting reference value by
GAIN operation, IPGA does not become the larger than the reference value.
For example, when REF=30H, RATT=2 step, IPGA=2FH, IPGA will become 2FH + 2step =
31H by auto recovery operation, but IPGA value becomes 30H as REF value is 30H.
IPGA should be certainly set to the same value or smaller than REF value before entering
full-auto mode .
