When the FDC sequences through the channels in multi-channel mode, the dwell time interval for each channel
is the sum of three parts:
1. sensor activation time
2. conversion time
3. channel switch delay
The sensor activation time is the amount of settling time required for the sensor oscillation to stabilize, as shown
in Figure 13. The settling wait time is programmable and should be set to a value that is long enough to allow
stable oscillation. The settling wait time for channel x is given by:
tSx = (CHX_SETTLECOUNTˣ16)/fREFx
(3)
Table 5 illustrates the registers and values for configuring the settling time for each channel.
