The µDMA can be programmed to read from flash. The Flash DMA Address Size (FLASHDMASZ) register configures 2KB regions of flash that can be accessed by the µDMA. The starting address for this µDMA-accessible region is defined in the Flash DMA Starting Address (FLASHDMAST) register. When the DFA bit is set in the FLASHPP register, the µDMA can access the enabled region configured by the FLASHDMASZ and FLASHDMAST registers. The µDMA checks the Flash Protection Program Enable n (FMPPEn) registers for masked 2KB flash regions before initiating the transfer. If the access is out of range, then a bus fault is generated.
NOTE
The µDMA can only access flash in run mode (not available in low power modes).
