Table 20.4 A/D Conversion Time (Single Mode)
Note: Values in the table are the number of states.
20.4.4
A/D conversion can be externally triggered. When the TRGS1 and TRGS0 bits are set to 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 is set to 1 by software. Figure 20.6 shows the timing.
20.5
The A/D converter generates an interrupt (ADI) at the end of A/D conversion. The ADI interrupt
request can be enabled or disabled by the ADIE bit in ADCSR.
