5.4 A/D PACER RATE SELECTION

The A/D pacer rate is programmable as can be seen from the list of rates in Table 5-1

above. The per channel rate is a function of both the programmed pacer and the

number of channels being sampled. Table 5-2 shows the effects of number of channels

selected on the per-channel rate.
