For module clock f
ADC
= 24 MHz, the analog clock f
ADCI
frequency can be selected as
shown in
Table 33
.

As f
ADCI
cannot exceed 10 MHz, bit field CTC should not be set to 00
B
when f
ADC
is
24 MHz. During slow-down mode where f
ADC
may be reduced to 12 MHz, 6 MHz etc.,
CTC can be set to 00
B
as long as the divided analog clock f
ADCI
does not exceed
10 MHz. However, it is important to note that the conversion error could increase due to
loss of charges on the capacitors, if f
ADC
becomes too low during slow-down mode.

The analog-to-digital conversion procedure consists of the following phases:
Synchronization phase (t
SYN
)
Sample phase (t
S
)
Conversion phase
Write result phase (t
