Bit 7
RESET
Software Reset Bit
0 = Not Used
1 = Software Reset. All Mode Control Registers Are Reset to 00h. The ADC is momentarily placed in SLEEP mode. This bit is
automatically set back to zero at the end of the SPI write command. The reset register is write only. Data read back from the reset
register will be random.
Bits 6-0
Unused, Don’t Care Bits.

Power Down Control Bits
00 = Normal Operation
01 = Channel 1 in Normal Operation, Channel 2 in Nap Mode
10 = Channel 1 and Channel 2 in Nap Mode

Bit 3
CLKINV
Output Clock Invert Bit
0 = Normal CLKOUT Polarity (As Shown in the Timing Diagrams)
1 = Inverted CLKOUT Polarity
Bits 2-1
CLKPHASE1:CLKPHASE0
Output Clock Phase Delay Bits
00 = No CLKOUT Delay (As Shown in the Timing Diagrams)
01 = CLKOUT+/CLKOUT– Delayed by 45° (Clock Period 1/8)
10 = CLKOUT+/CLKOUT– Delayed by 90° (Clock Period 1/4)
11 = CLKOUT+/CLKOUT– Delayed by 135° (Clock Period 3/8)
Note: If the CLKOUT Phase Delay Feature Is Used, the Clock Duty Cycle Stabilizer Must Also Be Turned On
Bit 0
DCS
Clock Duty Cycle Stabilizer Bit
0 = Clock Duty Cycle Stabilizer Off
1 = Clock Duty Cycle Stabilizer On
