Section 11 8-Bit Timers
11.7
11.7.1
The 8-bit timer can generate three types of interrupt: CMIA, CMIB, and OVI. Table 11.2 shows
the interrupt sources and priority. Each interrupt source can be enabled or disabled independently
by interrupt enable bits in TCR. Independent signals are sent to the interrupt controller for each
interrupt. It is also possible to activate the DTC by means of CMIA and CMIB interrupts.
Table 11.2 8-Bit Timer Interrupt Sources
11.7.2
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.
