• Bit 7 – POS23 : PSCOUT23 Selection (PSC2 only)
When this bit is clear, PSCOUT23 outputs the waveform generated by Waveform Generator B.
When this bit is set, PSCOUT23 outputs the waveform generated by Waveform Generator A.
• Bit 6 – POS22 : PSCOUT22 Selection (PSC2 only)
When this bit is clear, PSCOUT22 outputs the waveform generated by Waveform Generator A.
When this bit is set, PSCOUT22 outputs the waveform generated by Waveform Generator B.
• Bit 5:4 – PSYNCn1:0: Synchronization Out for ADC Selection
Select the polarity and signal source for generating a signal which will be sent to the ADC for
synchronization.
