REGISTER MAP
*End user should never neither read nor write this register.
INPUT CONTROL
This register allows the setting of the input stage as follows:
INxC sets up the configuration on each input. NCP2704 brings the flexibility to set up each input pair for a differential input
signal or two single−ended ones.
− 1 = Inputs are set as differential input with InxA as the positive and InxB as the negative.
− 0 = Inputs are set as stereo single−ended input with InxA as left input and InxB as right input.
12 different registers can be addressed through the “Register Address” byte.
