The transmitter can generate the following interrupts:
- Frame Done (FRAME_DONE)
This event indicates that FSI has completed transmitting a frame. - Buffer Underrun (BUF_UNDERRUN)
This event indicates that the transmit buffer has experienced underrun. Buffer underrun occurs when the transmitter tries to read data from a location which has not yet be written to by the CPU, or DMA. - Buffer Overrun (BUF_OVERRUN)
The buffer overrun interrupt is generated when the buffer has experienced overrun. Buffer overrun may occur if a piece of data is overwritten before it has been transmitted. - Ping Frame Triggered (PING_TRIGGERED)
The ping frame triggered interrupt is generated when the ping frame has been triggered. This bit will be set when the ping counter has timed out or an external ping trigger event has occurred.
