Initialise the PIO pins of the Codec
Initialise IIC
Write the data to be written to the PHY-chip to the link chip first
Wait until the link chip indicates that the data has been written to the PHY
Write the PHY-access register in the Link chip to indicate PHY read access
Wait until the link chip has obtained the value from the PHY-chip
Test whether the value read back equals the one previously written
Description
Communicating with the physical layer IC succeeded
The physical layer IC was not accessible
Communicating with the physical layer IC failed
Result of nucleus not according to HW diversity string
Initialise the DMA to transfer 5 frames PAL/NTSC
Initialise the DV de-multiplexer
Initialise the 1394 interface and start reception of the DV stream
Check whether the stream was copied to memory properly by the byte
input interface (port to memory type DMA)
Description
Routing the signals succeeded
The 1394 link chip could not be initialised properly
There was a syntax error in the DV stream
DMA could not copy DV stream to memory. Stream connected?
DMA not working properly
Initialise the 1394 interface
Detect whether a node is in range
Description
The node was detected OK
The 1394 link chip could not be initialised properly
Unable to write to 1394 PHY chip
Unable to read from 1394 PHY chip
No node was detected
