10.3.9 DMA Request Timing Diagram
10.3.9.1
Table 20 lists DMA request timing parameters and Figure 30 shows the DMA request timing
diagram in Asynchronous data transfer.
Notes: 1. Applies to EDGE mode only. The DMARQ# pulse width can be configured by SW.
10.3.9.2
Table 21 lists DMA request timing parameters and Figure 31 shows the DMA request timing
diagram in Synchronous data transfer.
Notes: 1. Applies to EDGE mode only. The DMARQ# pulse width can be configured by SW.
