D7:RSTAD
0:Normal operation
1:ADC Reset
In the case of not using ADC, set this value to “1” and ADC will be in RESET.
This can be useful for saving power consumption.
The digital output signals of ADC will 00000h.
When changing to normal operation, set this value to “0” at system reset.

1:SDINA select
In the case of internal connection (OPCL=”L”) and set this D4 to “1”, the SDINA path will connect to DSP directly.
(Its format is MSB justified 24-bit, or in the case of setting I2S then I2S)
If this setting selected, ADC can not use, so D7 should be set to “1”.

This DSP has a single feedback type shift-register [24,21,19,18,17,16,15,14,14,19,9,5,1] s independently from
calculation block.
This register changes the data in every sampling time. And its output connected with DBUS, so in case of selected
MSRG command at program code, then 24-bit random data will appear in every sampling.
In the case of using this random number generator, please set D1=1.
D0: Always input 0
Note) Underlines of the setting of
~
mean default setting.
