Nucleus Name
DS_DVIO_PhyDevTypeGet
Nucleus Number 701
Description Get the device (revision) type information of the 1394 Physical layer IC
Technical - Initialise the PIO pins of the Codec
- 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
- Read this out and filter the data to be returned to the user
Execution Time Less than 1 second
User Input None
Error Number Description
70100 Getting the information from the physical layer IC succeeded
70101 The physical layer IC was not accessible
70102 Getting the information from the physical layer IC failed
70103 Type not according to type stored in HW diversity
Example
DS:> 701
070100: Physical layer IC: VendorID: 0x006037, ProductID: 0x412801
Test OK @

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
70301 The physical layer IC was not accessible
70302 Communicating with the physical layer IC failed
70303 Result of nucleus not according to HW diversity string
Example
DS:> 703
