Profile Registers
There are eight consecutive serial I/O addresses (Address 0x0E
to Address 0x015) dedicated to device profiles. All eight profile
registers are either single tone profiles or RAM profiles. RAM
profiles are in effect when CFR1<31> = 1. Single tone profiles
are in effect when CFR1<31> = 0, CFR2<19> = 0, and CFR2<4>
= 0. In normal operation, the active profile register is selected
using the external PROFILE<2:0> pins. However, in the specific
case when CFR1<31> = 1 and CFR1<20:17> ≠ 0000
2
, the active
profile is selected automatically (see the RAM Ramp Up
Internal Profile Control Mode section).
Profile 0 to Profile 7—Single Tone Register
Address 0x0E to Address 0x15, 8 bytes are assigned to this register.

Profile 0 to Profile 7—RAM Register
Address 0x0E to Address 0x15, 8 bytes are assigned to this register.
Explanation
This 14-bit number controls the DDS output amplitude.
This 16-bit number controls the DDS phase offset.
This 32-bit number controls the DDS frequency.

Explanation
16-bit address step rate value.
10-bit waveform end address.
10-bit waveform start address.
Effective only when the RAM mode is in ramp up.
0 = when the RAM state machine reaches the end address, it halts.
1 = when the RAM state machines reaches the end address, it jumps to the start address
and halts.
Effective only when in RAM mode, direct switch.
0 = zero-crossing function disabled.
1 = zero-crossing function enabled.
