Function Documentation

WUT_cb_status SUMT_bcFrame (  SUMT_BC *  bc, WUT_tmr *  timer )

Start a new bus frame. Starts the bus controller processing bus commands to send to the remote terminal. A one second frame timer is also started, so that once the current list of bus commands is processed, the BCRTM device is restarted the next second with the same command list. Parameters: bc  A device descriptor. timer  The WUT handle for the frame timer. Returns: WUT_K_STATE_CHANGE_YES.

Here is the call graph for this function:

void SUMT_bcIntr (  SUMT_BC *  bc  )

Interrupt handler for driver. Handles Summit bus controller device interrupts. A descriptor is allocated from the interrupt pool. The internal status register as well as the contents of the event log in shared memory are saved to the interrupt descriptor. The descriptor is placed on a queue to be handled by SUMT_bcTask() at a later time. Parameters: bc  A device descriptor.

Here is the call graph for this function:

void SUMT_bcMsg (  SUMT_BC *  bc  )

Processes a 1553 data message event. Responds to a Summit device interrupt indicating that a 1553 frame of commands has completed. Any work to prepare commands for the next frame is completed, and then the data messages from the current frame are serviced. Parameters: bc  A device descriptor.
