00H PDN & Mode Control
R/W
Default
PWN: Power Down Control
0 : Power down
1 : Normal operation (Default)
“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.
DEM1-0: De-emphasis Control (Table 12, 13)
Initial values are “01”.
DEAU: De-emphasis Auto Control
0 : Disable (Default)
1 : Enable
When DEAU bit = “1”, the de-emphasis filter is enabled automatically by sampling frequency and
pre-emphasis information in the channel status.
SMUTE: Soft Mute Control
0 : Normal operation (Default)
1 : SDTIO and SDTO soft mute
When SMUTE bit = “1”, SDTO and SDTIO outputs “L”.
TXE: TX Output enable
0 : Disable, TX outputs “L”.
1 : Enable (Default)
XTL1-0: Reference MCLK Frequency Select (Table 16)
Initial values are “11”.
