9. OPERATION
LSb’s of the SCI AICTRLn should be zero. The resulting frequencies F
sin
can be calculated from the
DAC samplerate F
s
and SCI AICTRL0 / SCI AICTRL1 using the following equation.
F
sin
= SCI AICT RLn × F
s
/65536
Sine sweep test can be started by writing 0x4022 to SCI AIADDR.
Both these tests use the normal audio path, thus also SCI BASS, differential output mode, and EarS-
peaker settings have an effect.
