DESCRIPTION

R32

(0020h)

Tone

Generator

9:8

TONE_OFFSET

[1:0]

Tone Generator Phase Offset

Sets the phase of Tone Generator 2

relative to Tone Generator 1

00 = 0 degrees (in phase)

01 = 90 degrees ahead

10 = 180 degrees ahead

11 = 270 degrees ahead

TONE2_OVD

Tone Generator 2 Override

0 = Disabled (1kHz tone output)

1 = Enabled (DC signal output)

The DC signal level, when selected, is

configured using TONE2_LVL[23:0]

TONE1_OVD

Tone Generator 1 Override

0 = Disabled (1kHz tone output)

1 = Enabled (DC signal output)

The DC signal level, when selected, is

configured using TONE1_LVL[23:0]

TONE2_ENA

Tone Generator 2 Enable

0 = Disabled

1 = Enabled

TONE1_ENA

Tone Generator 1 Enable

0 = Disabled

1 = Enabled

R33

(0021h)

Tone

Generator

15:0

TONE1_LVL

[23:8]

1000h

Tone Generator 1 DC output level

TONE1_LVL [23:8] is coded as 2’s

complement. Bits [23:20] contain the

integer portion; bits [19:0] contain the

fractional portion.

The digital core 0dBFS level corresponds

to 1000_00h (+1) or F000_00h (-1).

R34

(0022h)

Tone

Generator

7:0

TONE1_LVL [7:0]

00h

Tone Generator 1 DC output level

TONE1_LVL [23:8] is coded as 2’s

complement. Bits [23:20] contain the

integer portion; bits [19:0] contain the

fractional portion.

The digital core 0dBFS level corresponds

to 1000_00h (+1) or F000_00h (-1).

R35

(0023h)

Generator

15:0

TONE2_LVL

[23:8]

1000h

Tone Generator 2 DC output level

TONE2

_LVL [23:8] is coded as 2’s

complement. Bits [23:20] contain the

integer portion; bits [19:0] contain the

fractional portion.

The digital core 0dBFS level corresponds

to 1000_00h (+1) or F000_00h (-1).

R36

(0024h)

Tone

Generator

7:0

TONE2_LVL [7:0]

00h

Tone Generator 2 DC output level

TONE2

_LVL [23:8] is coded as 2’s

complement. Bits [23:20] contain the

integer portion; bits [19:0] contain the

fractional portion.

The digital core 0dBFS level corresponds

to 1000_00h (+1) or F000_00h (-1).
