Configuring the UDC Module’s Registers 3-11
UDC Module Communication Status Register (Continued) 80/1080
Multiplexed Data Verification Failure Bit 9
The Multiplexed Data Verification Failure bit
is set if data which is multiplexed into
command/feedback messages does not
verify correctly. Hex Value: 0200H
Sug. Var. Name: N/A
Access: Read only
UDC Error Code: N/A
LED: N/A
No Matching PMI Operating System Present Bit 10
The No Matching PMI Operating System
Present bit is set if the correct PMI operating
system is not present in the UDC module’s
operating system and the PMI is requesting
an operating system. Hex Value: 0400H
Sug. Var. Name: N/A
Access: Read only
Sug. Var. Name: VDC_RUN@
UDC Error Code: N/A
LED: N/A
This condition will cause the loading of the PMI operating system to fail. However,
the UDC module and the PMI will continue to retry loading the PMI operating
system.
Invalid PMI Operating System Header Bit 11
The Invalid PMI Operating System Header
bit is set if the UDC module cannot locate a
valid PMI operating system header when
attempting to load an operating system to a
PMI. Hex Value: 0800H
Sug. Var. Name: N/A
Access: Read only
UDC Error Code: N/A
LED: N/A
This condition will cause the loading of the PMI operating system to fail. However,
the UDC module and the PMI will continue to retry loading the PMI operating
system.
Incompatible PMI Hardware Bit 12
The Incompatible PMI Hardware bit is set if
the PMI hardware is not compatible with the
PMI operating systems in the UDC
operating system. Hex Value: 1000H
Sug. Var. Name: N/A
Access: Read only
UDC Error Code: N/A
LED: N/A
UDC Module Receive Count Register 81/1081
This register contains the number of messages received by the UDC
module from the PMI. This is a 16-bit value that rolls over when it
reaches its maximum. Sug. Var. Name: N/A
Units: Counts
Range: 0-32000
