Table 14 DRC1 Control Registers

The WM5102 performs automatic checks to confirm that the SYSCLK frequency is high enough to

support the commanded DRC and digital mixing functions. If an attempt is made to enable a DRC

signal path, and there are insufficient SYSCLK cycles to support it, then the attempt will be

unsuccessful. (Note that any signal paths that are already active will not be affected under these

circumstances.)

The Underclocked Error can be monitored using the GPIO and/or Interrupt functions. See “General

Purpose Input / Output” and “Interrupts” for further details.

The FX_STS field in Register R3585 indicates the status of each of the EQ, DRC and LHPF signal

paths. If an Underclocked Error condition occurs, then this register provides readback of which EQ,

DRC or LHPF signal path(s) have been successfully enabled.

The status bits in Registers R1600 to R2920 indicate the status of each of the digital mixers. If an

Underclocked Error condition occurs, then these bits provide readback of which mixer(s) have been

successfully enabled.
