2.6.5.2 DMA Data Transfers
Table 2-18 describes the DMA signal timing.
The DREQ
signal is synchronized with the falling edge of DLLIN. DONE timing is relative to the rising edge of DLLIN.
To achieve fast response, a synchronized peripheral should assert DREQ according to the timings in Table 2-18.
Figure 2-11 shows synchronous peripheral interaction.
Table 2-18.
