Section 15 A/D Converter
Table 15.3 A/D Conversion Characteristics (Single Mode)
Note:
Table 15.4 A/D Conversion Characteristics (Scan Mode)
15.4.4
A/D conversion can be externally triggered. When the TRGS1 and TRGS0 bits are set to B'11 in
ADCR, an external trigger is input from the ADTRG0 pin. A/D conversion starts when the ADST
bit in ADCSR is set to 1 on the falling edge of the ADTRG0 pin. Other operations, in both single
and scan modes, are the same as when the ADST bit has been set to 1 by software. Figure 15.5
shows the timing.
