Section 20 A/D Converter (ADC)

Table 20.5 A/D Conversion Time (Multi Mode and Scan Mode)

Note: Values in the table are the numbers of states.

A/D conversion can also be externally triggered. When the TRGS[3:0] bits in ADCSR are set to

B'1001, an external trigger is input to the ADTRG pin. The ADST bit in ADCSR is set to 1 at the

falling edge of the ADTRG pin, thus starting A/D conversion. Other operations, regardless of the

operating mode, are the same as when the ADST bit has been set to 1 by software. Figure 20.6

shows the timing.
