Section 15 Serial Communication Interface (SCI, IrDA)
When performing transfer using the DTC or DMAC, it is essential to set and enable the DTC or
DMAC before carrying out SCI setting. For details on the DTC or DMAC setting procedures,
refer to section 9, Data Transfer Controller (DTC) or section 7, DMA Controller (DMAC).
In receive operations, an RXI interrupt request is generated when the RDRF flag in SSR is set to
1. If the RXI request is designated beforehand as a DTC or DMAC activation source, the DTC or
DMAC will be activated by the RXI request, and transfer of the receive data will be carried out.
The RDRF flag is cleared to 0 automatically when data transfer is performed by the DTC or
DMAC. If an error occurs, an error flag is set but the RDRF flag is not. Consequently, the DTC or
DMAC is not activated, but instead, an ERI interrupt request is sent to the CPU. Therefore, the
error flag should be cleared.
