Note: For addresses from 0FH to 1FH, data must not be written.
When the RSTB pin goes “L”, the registers are initialized to their default values.
When RSTN bit is set to “0”, only the internal timing is reset, and the registers are not initialized to their default
values. All data can be written to the registers even if PW4-1 bits or RSTN bit is “0”.

RSTN: Internal timing reset
0: Reset. All DZF pins change to “H” and any registers are not initialized.
1: Normal operation
When MCLK frequency or DFS changes, the click noise can be reduced by RSTN bit.
PW1: Power-down control (0: Power-down, 1: Power-up)
PW1: Power down control of DAC1
This bit is duplicated into D1 of 02H.
DIF2-0: Audio data interface modes (Table 8)
