The RTDMA contains overrun detection logic. When the burst for a channel is started, the PERINTFLG is cleared. If however, between the time that the PERINTFLG bit is set by an event trigger and cleared by the start of the burst, an additional event trigger arrives, and the second trigger is lost. This condition sets the OVRFLG bit in the CONTROL register as in Figure 12-7. If the overrun interrupt is enabled, the channel interrupt is generated to the Interrupt Controller module.
