IPGA6-0:
IPGA Control
When AGC bit is set to "0", IPGA value can be changed by the write operation to this register via A/T I/F directly.
When AGC bit is set to "1", The write to IPGA register is ignored. The AK4533 outputs updated value when the read operation is
processed.

REF6-0:
Recovery Reference Level
This value specifies the upper reference level of Recovery Operation when AGC is activated.
IPGA value is forced to set the same value as Recovery Reference Level when IPGA tries to exceed Recovery Reference Level under
Recovery Operation. Therefore, IPGA is not greater than Recovery Reference Level.
Write the appropriate value when AGC bit is set to "0". Must NOT change this value while AGC is active.
