Note: For addresses from 0FH to 1FH, data must not be written.
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 bits or RSTN bit is “0”.

RSTN: Internal timing reset
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.
PW1: Power-down control (0: Power-down, 1: Power-up)
PW1: Power down control of DAC1
This bit is duplicated into D1 of 02H.

ACKS: Master Clock Frequency Auto Setting Mode Enable
0: Disable, Manual Setting Mode
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically when the ACKS bit = “1”. In this case, the setting of
DFS1-0 bits is ignored. When this bit is “0”, DFS1-0 bits set the sampling speed mode.
