13.4.5
The A/D converter can be independently activated by an A/D conversion request from the interval
timer of the MTU or MMT.
To activate the A/D converter by the MTU or MMT, set the A/D trigger select register (ADTSR).
After this register setting has been made, the ADST bit in ADCR is automatically set to 1 when an
A/D conversion request from the interval timer of the MTU or MMT occurs. The timing from
setting of the ADST bit until the start of A/D conversion is the same as when 1 is written to the
ADST bit by software.
13.4.6
A/D conversion can be externally triggered. When the TRGS0 and TRGS1 bits are set to 00 or 01
in ADTSR, external trigger input is enabled at the ADTRG pin. A falling edge of the ADTRG pin
sets the ADST bit to 1 in ADCR, starting A/D conversion. Other operations, in both single and
scan modes, are the same as when the ADST bit has been set to 1 by software. Figure 13.3 shows
the timing.
