Table 108. Sample and Settling Time (ADCSST)
The Sample Settling Time Register, shown in Table 108, is used to program the length of
time from the SAMPLE/HOLD signal to the START signal, when the conversion can
begin. The number of clock cycles required for settling will vary from system to system
depending on the system clock period used. The system designer should program this reg-
ister to contain the number of clocks required to meet a 0.5 µs minimum settling time.
The Sample Time Register, shown in Table 109, is used to program the length of active
time for the sample after a conversion has begun by setting the START bit in the ADC
Control Register or initiated by the PWM. The number of system clock cycles required for
sample time varies from system to system, depending on the clock period used. The sys-
tem designer should program this register to contain the number of system clocks required
to meet a 1 µs minimum sample time.
