14.4.4
External Trigger Input Timing
A/D conversion can be externally triggered When the TRGE bit is set to 1 in ADCR and the 8-bit
timer's ADTE bit is cleared to 0, external trigger input is enabled at the
ADTRG
pin. A high-to-
low transition 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 if the ADST bit had been set to 1
by software. Figure 14.6 shows the timing.
