Nucleus Name DS_DVIO_PhyCommunication
Nucleus Number 703
Description Check the accessibility of the 1394 Physical layer IC by writing to and reading
from a specific address
Technical - 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
Execution Time Less than 1 second
User Input None
Error Number Description
70300 Communicating with the physical layer IC succeeded
