Section 15 A/D Converter
15.5.4
A/D conversion can be externally triggered. When the TRGS0 and TRGS1 bits are set to 11 in
ADCR, external trigger input is enabled at the ADTRG pin. A falling edge 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 when the bit ADST has been set to 1 by software. Figure 15.6 shows the
timing.
15.6
The A/D converter generates an A/D conversion end interrupt (ADI) at the end of A/D conversion.
Setting the ADIE bit to 1 enables ADI interrupt requests while the bit ADF in ADCSR is set to 1
after A/D conversion is completed. In the H8S/2268 Group, the DTC * can be activated by an ADI
interrupt. Having the converted data read by the DTC * in response to an ADI interrupt enables
continuous conversion without imposing a load on software.

Note: * Supported only by the H8S/2268 Group.
