Selects the Type of Waveform.
00 Direct write to DAC. User code writes to the HSDACDAT register directly.
10 Sinusoid. Set AFECON, Bit 4 to 1, set this bit to 10, and the DAC outputs a sine wave.

Sinusoid Phase Offset. SINOFFSET, Bits[19:0] = phase (degrees)/360 × 2
example, to achieve a 45° phase offset, SINOFFSET, Bits[19:0] = 45/360 × 2
MMR must be set before setting WGCON, Bits[2:1] and AFECON, Bit 14.
Description
Reserved.
Sinusoid Offset. Added to the waveform generator output in sinusoid mode. Signed
number represented in twos complement format. This MMR must be set before setting
WGCON, Bits[2:1] and AFECON, Bit 14.

Reserved.
Sinusoid Amplitude. Unsigned number. Scales the waveform generator in
sinusoid mode. The DAC output voltage is determined by the value in
HSDACCON, Bit 0 and HSDACCON, Bit 12. This MMR must be set before setting
WGCON, Bits[2:1] and AFECON, Bit 14.
