SRC Mute Register (SRCMUTE)

This read-write register, described in Table A-44, connects an SRCx mute

input and output (when cleared) to automatically mute input while the

SRC is initializing. Bit 0 controls SRC0, bit 1 controls SRC1, bit 2 controls

SRC2, and bit 3 controls SRC3. This register is located at address 0x2492.

Note that the SRC mute interrupts are latched in the DAI_IRPTL_H and

DAI_IRPTL_L registers.
