1.3.11.3 Sampling Rate Calculation for Fusion

The inverse of the conversion time is the sampling rate for that channel. However, the sampling rate reported by ASB includes the time that the ASSC can process the data and assert another start conversion signal. This time is referred to as ‘turnaround time’. With no wait states, the ASSC takes 10 system clock cycles for turnaround time.

Therefore, in the case of Fusion, the sampling rate of a single channel is: 1 / [ ( ASSC turnaround time ) + ( channel conversion time ) ]

ASSC Turnaround Time is defined as the number of flags for a channel may increase the turnaround time of the ASSC. Increasing the number of flags will potentially reduce your max sampling rate.
