All of the above interrupts can be enabled and disabled by setting or resetting the
corresponding bits in the IntEnable register. Enabling or disabling does not affect the
IntStatus register contents, only the propagation of the interrupt status to the CPU (via the
NVIC).
The interrupts, either of individual frames or of the whole list, are a good means of
communication between the DMA manager and the device driver, triggering the device
driver to inspect the status words of descriptors that have been processed.

of 8 bytes and a frame payload of 12 bytes.
After reset the values of the DMA registers will be zero. During initialization the device
driver will allocate the descriptor and status array in memory. In this example, an array of
four descriptors is allocated; the array is 4x2x4 bytes and aligned on a 4 byte address
•
In the case of a transmission error (LateCollision, ExcessiveCollision, or
ExcessiveDefer) or a multi-fragment frame where the device driver did provide the
initial fragments but did not provide the rest of the fragments (NoDescriptor) or in the
case of a nonfatal overrun, the hardware will set the TxErrorInt bit of the IntStatus
register.
