BF706 DMA function

Hi,

1) Regarding, "I don't know how the DMA occurs and how this function works, where is the interrupt source."

>> www.analog.com/.../BF70x_BlackfinProcessorHardwareReference.pdf

2) The below API can be used to install an interrupt handler for a given processor interrupt.

ADI_INT_STATUS adi_int_InstallHandler (
uint32_t iid,
ADI_INT_HANDLER_PTR pfHandler,
void * pCBParam,
bool bEnable )


It is a valid API for system interrupts, core interrupts, NMI, and hardware exceptions. The API takes the following arguments:

•iid - Interrupt ID. For system interrupts this is the system interrupt ID (also referred to as peripheral interrupt ID in the Hardware Reference manuals). This is a unique number to identify a particular interrupt. Refer to the Hardware Reference manual for your processor to find the number for a specific interrupt.

•pfHandler - Handler which handles the interrupt. This handler will be called when the interrupt occurs.

•pCBParam - Application-provided callback parameter, which is passed back when the given handler is called.

•bEnable - Flag, which indicates whether to enable or disable the given interrupt, after the interrupt handler installation. The interrupt can be disabled during the installation and enabled later by calling adi_int_EnableInt().This argument should be set to:

◦true to enable the interrupt

◦false to disable the interrupt
