Linear Sweep Parameter Register
Address 0x06, 8 bytes are assigned to this register. This register is only effective if CFR1 [11] or CFR1 [28] are set. See the Auxiliary
Accumulator section.

Bit Name
Description
63:32
Sweep Parameter Word 0
32-bit linear sweep upper limit value. In modulus mode, these bits set the auxiliary
accumulator capacity
31:0
Sweep Parameter Word 1
32-bit linear sweep lower limit value. In modulus mode, these bits set the base FTW.
Linear Sweep Delta Parameter Register
Address 0x07, 8 bytes are assigned to this register. This register is only effective if CFR1 [11] or CFR1 [28] are set. See the Auxiliary
Accumulator section.

Description
63:32
Falling Delta Word
32-bit linear sweep decrement step size value.
31:0
Rising Delta Word
32-bit linear sweep increment step size value. In modulus mode, these bits set the auxiliary
accumulator seed value.
Linear Sweep Ramp Rate Register
Address 0x08, 4 bytes are assigned to this register. This register is only effective if CFR1 [11] or CFR1 [28] are set. See the Auxiliary
Accumulator section.

Bit(s)
Bit Name
Description
31:16
Falling Sweep Ramp Rate
16-bit linear sweep negative slope value that defines the time interval between decrement
values.
15:0
Rising Sweep Ramp Rate
16-bit linear sweep positive slope value that defines the time interval between increment
values.

Profile Registers
There are eight consecutive serial I/O addresses dedicated to device profiles. In normal operation, the active profile register is selected
using the external profile select pins.
Profile 0 to Profile 7—Single Tone Register
Address 0x09 to Address 0x10, 6 bytes are assigned to these registers.

Phase Offset Word
This 14-bit number controls the DDS phase offset.
31:0
Frequency Tuning Word
This 32-bit number controls the DDS frequency.
