AD6649
SYNC Pin Control (Register 0x59)
Bits[7:2]—Reserved
Bit 1—SYNC Pin Sensitivity
If Bit 1 is set to a 0, the SYNC input responds to a level. If this
bit is set low, the SYNC input responds to the edge (rising or
falling) set in Bit 0 of Address 0x59.
Bit 0—SYNC Pin Edge Sensitivity
If Bit 1 is set high, setting Bit 0 to a 0 causes the SYNC input to
respond to a falling edge. If this bit is set, the SYNC input
respond to a rising edge.

NCO Control 2 (Register 0x5A)
Bits[7:1]—Reserved
Bit 0—Low Latency NCO Select
If Bit 0 is set to a 1, the low latency NCO is selected. This bit
should be selected for the fixed-frequency NCO, 95 MHz FIR
filter mode of operation. When this bit is set, the NCO value
must be set to either 0x40000000 or 0xC0000000.
