Table 22.6 A/D Conversion Time (Scan Mode) (Unit 1)
22.4.4
A/D conversion can be externally triggered. For unit 0, an external trigger is input from the
ADTRG0 pin when the TRGS1, TRGS0, and EXTRGS bits are set to B'110 in ADCR_0. For unit
1, an external trigger is input from the ADTRG1 pin when the TRGS1, TRGS0, and EXTRGS bits
are set to B'110 in ADCR_1. A/D conversion starts when the ADST bit in ADCSR is set to 1 on
the falling edge of the ADTRG 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 22.7 shows the timing.
Also, A/D conversion for multiple units can be externally triggered (multiple units can start
simultaneously). For units 0 and 1, an external trigger is input from the ADTRG0 pin when the
TRGS1, TRGS0, and EXTRGS bits are set to B'111 in ADCR_0 and ADCR_1. A/D conversion
starts when the ADST bit in ADCSR is set to 1 on the falling edge of the ADTRG pin. The timing
is different from the one when multiple units do not start simultaneously. Figure 22.8 shows the
timing.
