INTERCHANNEL DELAY REGISTERS (0x11, 0x12, 0x13, and 0x14)

Internal PWM Channels 1, 2, 1, and 2 are mapped into registers 0x11, 0x12, 0x13, and 0x14.

ICD settings have high impact on audio performance (e.g.: dynamic range, THD, crosstalk, etc.) Therefore,

appropriate ICD settings must be used. By default, the device has ICD settings for AD mode. If used in BD

mode, then update these registers before coming out of all-channel shutdown.
