7734M–AVR–03/10
Analog Synchronization Delay Register – PASDLYn
PSC 2 Control Register – PCTL2
• Bit 0– PISELnB1: PSC n Input Select for part B
Together with PISELnB0, defines active signal on PSC part B.
Table 13-19.
The Analog Synchronization Delay Register store an 8 bit delay used:
See also the bit definition Section “Bit 7, 6, 5– PASDLKn(2:0): Analog Synchronization Output Delay or
Input Blanking select”, page 136 and Section “Bit 5:4 – PSYNCn1:0: Synchronization Out for ADC
Selection”, page 133
• Bit 7:6 – PPREn1:0 : PSC n Prescaler Select
This two bits select the PSC input clock division factor.All generated waveform will be modified by this
factor.
