Section 12 8-Bit Timers
12.4
12.4.1
There are three 8-bit timer interrupt sources: CMIA, CMIB, and OVI. Their relative priorities are
shown in table 12.3. Each interrupt source is set as enabled or disabled by the corresponding
interrupt enable bit in TCR, 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.
Table 12.3 8-Bit Timer Interrupt Sources
Channel
0
1
Note: This table shows the initial state immediately after a reset. The relative channel priorities
12.4.2
The A/D converter can be activated only by channel 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 channel
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.
