1. General DMA Issues & Workarounds

️· DAX Interrupt Handling (ES119): If disabling DAX interrupts, a specific sequence involving clearing interrupt request bits, NOP instructions, and then clearing the enable bits is necessary to prevent an unknown interrupt vector from being generated. This is particularly important.
️· Simultaneous Core/DMA Access (ES132): Avoid concurrent DMA and core memory access to the same 1/4K page of internal memory when operating above 90MHz.
️· DMA & Core Access to Shared Memory (ES115): When disabling a DMA channel, a complex workaround involving initialization of a "dummy" DMA channel is required to prevent incorrect status flag setting.
️· DMA writes to HTX (ES130): A known bug where HTDE status is not immediately set. No data is lost, but latency increases.

2. DMA Configuration & Addressing

️· Triple Counter Mode (ES114): If using three-dimensional addressing (D3D=1), avoid triple counter modes E. Use modes C or D instead.

3. Host DMA Issues

️· ICR Register (ES129): A bug in the Host DMA functionality where bits 6 and 5 of the ICR register don't accurately reflect HDM[1-0]. Read HDM[2-0] in the HCR register to determine operating mode.

4. Timing and Synchronization Issues

️· HTDE Status (ES130): As mentioned previously, the HTDE status is delayed. This affects timing and synchronization.

5. Frequency-Dependent Issues

️· Core/DMA Simultaneous Access (ES132): The frequency-dependent core/DMA memory access issue becomes relevant at frequencies above 90MHz.

Important Considerations & Next Steps:

️· Masking: Depending on the application, some of these errata might be masked (ignored) if their effects aren't encountered.
️· Application Impact: Carefully evaluate how each erratum's workaround affects the overall system performance and complexity. Some workarounds introduce overhead.
️· Frequency: Pay close attention to any frequency-dependent issues, particularly when operating at higher speeds.
️· Documentation: Refer to the full errata documentation from Motorola/Freescale for complete details and potentially more nuanced explanations. This summary is based solely on the provided text.
️· Freescale/NXP: As Motorola has been acquired by NXP, consult the NXP website for the latest information and support.
