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.
