SCIF: Serial communication interface with FIFO
Notes: 1. SCI/SCIF burst transfer setting is prohibited.
To output a transfer request from an on-chip peripheral module, set the DMA transfer request
enable bit for that module and output a transfer request signal.
For details, see sections 12, Timer Unit (TMU), 15, Serial Communication Interface (SCI), and
16, Serial Communication Interface with FIFO (SCIF).
