Section 22 Serial Communication Interface with FIFO (SCIF)
22.6.4 Using the DMAC
When performing transmission/reception using the DMAC, the SCIF should be configured such
that the RXI and TXI interrupt requests are not sent to the interrupt controller. If not configured as
such, however, the interrupt requests sent to the interrupt controller will be cleared by the DMAC
regardless of the interrupt handling program.
22.6.5 Interrupts
Although the SCIF has four types of interrupt sources for each channel, only a single INTEVT
code is assigned per channel. Therefore, interrupt sources must be identified by software.
