13.7
13.7.1
There are three 8-bit timer interrupt sources: CMIA, CMIB, and OVI. Their relative priorities are
shown in table 13.4. Each interrupt source is set as enabled or disabled by the corresponding
interrupt enable bit in TCR or TCSR, and independent interrupt requests are sent for each to the
interrupt controller. It is also possible to activate the DTC by means of CMIA and CMIB
interrupts.

13.7.2
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.
