Table 16.4 SCIF Interrupt Sources
Notes: 1. The DMAC can be activated only by a receive-FIFO-data-full interrupt request.
See section 4, Exception Handling, for priorities and the relationship with non-SCIF interrupts.
Rev. 1.00, 02/04, page 486 of 804
Description
Interrupt initiated by receive error flag (ER) or break flag (BRK)
Interrupt initiated by receive FIFO data full flag (RDF)
or receive data ready (DR)
Interrupt initiated by transmit FIFO data
empty flag (TDFE) or transmit data stop flag (TSF)
2. The DMAC can be activated by a transmit-FIFO-data-empty (TDFE) or transmit-data-
stop (TSF) interrupt request. When the DMAC is activated by the TSF interrupt, it is
cleared by either of two cases listed below.
(1) The TSF flag is read by the CPU.
(2) The transmit FIFO is full.
