Table 21.3 A/D Conversion Time (Single Mode)
Note:
21.4.4
A/D conversion can be externally triggered. When the TRGS1 and TRGS0 bits are set to B’11 in
ADCR, external trigger input is enabled at the ADTRG pin. A falling edge at the ADTRG pin sets
the ADST bit to 1 in ADCSR, starting A/D conversion. Other operations, in both single and scan
modes, are the same as when the ADST bit has been set to 1 by software. Figure 21.4 shows the
timing.
