Section 17 A/D Converter
17.4.3
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input when the A/D conversion start delay time (t
1, then starts A/D conversion. Figure 17.6 shows the A/D conversion timing. Tables 17.5 and 17.6
show the A/D conversion time.
As shown in figure 17.6, the A/D conversion time (t
time (t
write access to ADCSR. The total conversion time therefore varies within the ranges indicated in
tables 17.5 and 17.6.
In scan mode, the values given in tables 17.5 and 17.6 apply to the first conversion time. The
values given in table 17.7 apply to the second and subsequent conversions. In either case, bit
EKCKS in ADCSR, and bits CKS1 and CKS0 in ADCR should be set so that the conversion time
is within the ranges indicated by the A/D conversion characteristics.
