A/D Converter Activation

The A/D converter can be activated only by TMR_0 compare match A.
If the ADTE bit in TCSR0 is set to 1 when the CMFA flag is set to 1 by the occurrence of TMR_0
compare match A, a request to start A/D conversion is sent to the A/D converter. If the 8-bit timer
conversion start trigger has been selected on the A/D converter side at this time, A/D conversion is
started.
