PW1: Power-down control (0: Power-down, 1: Power-up)
When RSTB pin goes to “L”, the registers are initialized to their default values.
When RSTN bit goes to “0”, the only internal timing is reset, and the registers are not initialized to their default
values. All data can be written to the registers even if PW1-4 bit or RSTN bit is “0”.
RSTN: Internal timing reset
DIF2-0: Audio data interface modes (See Table 8, Table 9, Table 10)

0: Reset. All DZF pins go 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.
Initial: “010”,
PW1: Power down control of DAC1
This bit is duplicated into D1 of 02H.
