Hi,
what are the differences between PL-330 and DMA-330?
Are they both support any byte alignment?
Br,
The DMAC product designator is either PL330 or DMA-330 and depends on the product revision as follows:
r0p0 PL330.
r1p0 or later DMA-330.
r0p0 - r1p0 This release includes:
• Precise lockup detection, see Watchdog abort on page 2-26.
• No store before load, see Abort sources on page 2-25.
• Addition of the WD Register, see Watchdog Register on page 3-40.
• Addition of the Add Negative Halfword instruction, DMAADNH, see DMAADNH on page 4-4.
You can find the detail information in DDI0424D_dma330_r1p2_trm.pdf from ARM official website.
Do you know if within single channel the transactions are in-order?
