Table 6.9 shows another example of MSCI-to-memory multi-frame transfer using four descriptors
and four buffers. In this example, to rewrite a buffer, the received data stored in the buffer is
moved to another area during reception operations, and EDA is updated. Steps 1 to 7 are the same
as those in table 6.8. Since the DMAC remains enabled after one frame has been transferred in
multi-frame transfer mode, some frame end interrupts (DMIB) might remain unprocessed. The
number of unprocessed interrupts is stored in the frame end interrupt counter (FCT). When the
FCT value is 1111 and frame transfer continues, a counter overflow error occurs, and the DMAC
terminates data transfer after transmitting the current frame. The FCT value is then reset to 0000,
and DMIA interrupt is generated (if enabled). For details, see sections 6.2.8, DMA Mode Register
(DMR), and 6.2.9, Frame End Interrupt Counter (FCT).
