Section 17 Serial Communication Interface with FIFO (SCIF)
17.5
SCIF Interrupt Sources and the DMAC
The SCIF has four interrupt sources: transmit-FIFO-data-empty interrupt (TXI) request, receive-
error interrupt (ERI) request, receive-FIFO-data-full interrupt (RXI) request, and break interrupt
(BRI) request.
Table 17.7 shows the interrupt sources and their order of priority. The interrupt sources are
enabled or disabled by means of the TIE, RIE, and REIE bits in SCSCR. A separate interrupt
request is sent to the interrupt controller for each of these interrupt sources.
If the TDFE flag in SCFSR is set to 1 when a TXI interrupt is enabled by the TIE bit, a TXI
interrupt request and a transmit-FIFO-data-empty request for DMA transfer are generated. If the
TDFE flag is set to 1 when a TXI interrupt is disabled by the TIE bit, only a transmit-FIFO-data-
empty request for DMA transfer is generated. A transmit-FIFO-data-empty request can activate
the DMAC to perform data transfer.
If the RDF or DR flag in SCFSR is set to 1 when an RXI interrupt is enabled by the RIE bit, an
RXI interrupt request and a receive-FIFO-data-full request for DMA transfer are generated. If the
RDF or DR flag is set to 1 when an RXI interrupt is disabled by the RIE bit, only a receive-FIFO-
data-full request for DMA transfer is generated. A receive-FIFO-data-full request can activate the
DMAC to perform data transfer. Note that generation of an RXI interrupt request or a receive-
FIFO-data-full request by setting the DR flag to 1 occurs only in asynchronous mode.
When the BRK flag in SCFSR or the ORER flag in SCLSR is set to 1, a BRI interrupt request is
generated.
If transmission/reception is carried out using the DMAC, set and enable the DMAC before making
the SCIF settings. Also make settings to inhibit output of RXI and TXI interrupt requests to the
interrupt controller. If output of interrupt requests is enabled, these interrupt requests to the
interrupt controller can be cleared by the DMAC regardless of the interrupt handler.
By setting the REIE bit to 1 while the RIE bit is cleared to 0 in SCSCR, it is possible to output
ERI interrupt requests, but not RXI interrupt requests.
