“0” powers down all sections. The contents of all register are not initialized and enabled to write to the
registers. The internal registers (00H ∼ 06H) are not initialized, however, the status registers (07H ∼ 1CH)
are initialized. Read/Write operations to the registers are enabled.
Initial values are “01”.
When DEAU bit = “1”, the de-emphasis filter is enabled automatically by sampling frequency and
pre-emphasis information in the channel status.
When SMUTE bit = “1”, SDTO and SDTIO outputs “L”.
Initial values are “11”.
