DM Com Prt Stat
Indicates faults or warnings related to the Drive Module’s
Drive Communication ports.
• Bit 0 [Bad Rcv Int] indicates the interrupt generated by
the Universal Serial Controller (USC) is not properly
marked
• Bit 1 [No EOF] indicates the USC did not report an End
of Frame condition when the recieve interrupt was
generated
• Bit 2 [CRC Error] indicates the USC has reported a
Cyclic Redundancy Check (CRC) error on the last frame
(message) received
• Bit 3 [Overrun Err] indicates the USC has reported a
receive firs-in, first out error
• Bit 4 [DMA Error] indicates the length of a received
message did not match the length encoded in the
message itself
• Bit 5 [Xmit Underun] indicates the USC has reported a
transmit first-in, first-out underrun
• Bit 6 [Sync Error] indicates two or more CCLK counter
ticks occurred and no message was recieved
• Bit 8 [DM Sync Err] indicates two or more CCLK counter
ticks occurred and no message was recieved
• Bit 9 [Multplx Err] indicates data which is multiplexed
into a command/feedback message has not verified
correctly
• Bit 12 [Bad Start Ad] indicates the operating system is
not within the allocated operating system address area

• Bit 13 [Bad PMI Mem] indicates there is insuffient
memory in the PMI processor for loading the operating
system
• Bit 14 [Bad Load Ad] indicates the address at which the
PMI processor is to load the operating system is invalid
• Bit 15 [PMI OverFlow] indicates the loading of the PMI
operating system will overrun the PMI stack memory
area
