Figure 18.9 Procedure for Changing the Mode When Setting for Activation by an External
Do not perform writing to change the value of the ADST bit in ADCSR from 0 to 1 when the
setting for activation by an external trigger is in use.
When the setting for activation by an external trigger is in use, only execute switching from
activation by an external trigger to prohibition of activation by an external trigger or changing
of the scan mode (ADSTLCR and SCANE bits) after external trigger input has been disabled.
External trigger input can be disabled by writing specific values to the TRGS1, TRGS0, and
EXTRGS bits in ADCR.
For details on the procedure in cases where point 2 or 3 is applicable, see figure 18.9.
Note: * Rewrite the TRGS1, TRGS0, and EXTRGS bits in ADCR simultaneously (in bytes).
