6.2.4.2.
The SigmaTel Surround on/off function will be typically controlled by the end-user.
End-user driven programming steps are shown in section 6.3.
The default WIDTH_CONTROL of 4 should be appropriate for most applications.
This optional programming step shows how to configure a different width value.
// Configure the surround width
// (0x0 = Least width, 0x7 = Most width).
// a width setting of 5
Modify DAP_SGTL_SURROUND->WIDTH_CONTROL 0x0005
6.2.4.3.
The SigmaTel Bass Enhance on/off function will be typically controlled by the end-
user. End-user driven programming steps are shown in section 6.3.
The default LR_LEVEL value of 0x0005 results in no change in the input signal level
and BASS_LEVEL value of 0x001F adds some harmonic boost to the main signal.
The default settings should work for most applications. This optional programming
step shows how to configure a different value.
// Gain up the input signal level
Modify DAP_BASS_ENHANCE_CTRL->LR_LEVEL 0x0002
// Add harmonic boost
Modify DAP_BASS_ENHANCE_CTRL->BASS_LEVEL 0x003F);
6.2.4.4.
Only one audio EQ block can be used at a given time. The psuedocode in this sec-
tion shows how to select each block.
Some parameters of the audio EQ will typically be controlled by end-user. End-user
driven programming steps are shown in section 6.3.
// 7-Band PEQ Mode
// Select 7-Band PEQ mode and enable 7 PEQ filters
Write DAP_AUDIO_EQ 0x0001
Write DAP_PEQ 0x0007
// Tone Control mode
Write DAP_AUDIO_EQ 0x0002
// 5-Band GEQ Mode
Write DAP_AUDIO_EQ 0x0003
