are initialized. Read/Write operations to the registers are enabled.
Initial values are “01”.

When SMUTE bit = “1”, SDTO and SDTIO outputs “L”.
“0” powers down all sections. The contents of all register are not initialized and enabled to write to the
When DEAU bit = “1”, the de-emphasis filter is enabled automatically by sampling frequency and
