Address “1” ; PCM_1/2 ---- Selection of the PCM interface Mode(Long/Short frame, AK130-1,AK130-2, 16bit linear)
Address ”6” ; L-ATT ---- -6dB attenuation for Tone generator-L output in case of DTMF tone generation.
Bits in which “0” is filled are for test mode activation. Please fill the data “0” for the normal operation.
Bits in which “-“ is filled are for test use and can not write the data from CPU interface. In case the read
operation, data “0” are read from CPU interface.
