GSi TYMPSTAR 1, Service Manual

Page: 206 / 224

Short Description Description
System RAM Test Failure System RAM is checked for integrity at reset.
Subcodes: Specific address that failed.
Likely Causes: Shorted data line, open data line, intermittent
address/control line, defective component at U30.
EPROM Checksum Mismatch The EPROM is checksummed at reset; this checksum is
compared to the one that is stored on the EPROM.
Subcodes: None.
Likely Causes: Corrupt EPROM at U28.
Divide by Zero If processor is instructed to divide by zero, this exception is
generated.
Subcodes: None.
Likely Causes: Corrupt calibration data in probe; noise
during calibration.
Non-Maskable Interrupt The processor received an interrupt from an unconnected
source.
Subcodes: None.
Likely Causes: Software error ,failed processor; U26.46
intermittent or shorted high.
Overflow Exception Register overflowed as a result of a math instruction.
Subcodes: None.
Likely Causes: Software error.
Array Bounds Exception If an array were indexed with an out of bounds value, the
processor would be instructed to generate this exception.
Subcodes: None.
Likely Causes: Software error.
Invalid Opcode Processor will generate this failure if it attempts to process an
invalid instruction.
Subcodes: None.
Likely Causes: Software error.
Escape Instruction Interrupt Processor will generate this failure if the ESC instruction is
executed. The software never instructs this in normal
operation.
Subcodes: None.
Likely Causes: Software error.
Undefined Interrupt Software interrupt that is not designated for any use.
Subcodes: None.
Likely Causes: Software error.
DMA Interrupt Processor generates this interrupt when a DMA operation
completes; however, DMA is not used in the TympStar, so
this should never occur.
Subcodes: None.
Likely Causes: Software error.
Unused Timer Interrupt Generated if an unused timer generates an interrupt.
Subcodes: None.
Likely Causes: Software error.
Invalid Real-Imaginary Buffer Index During Get The software ensures that the index used to retrieve real-
imaginary data from its memory array is bounds checked.
Subcodes: Index into buffer.
Likely Causes: Software error.
Invalid Pseudo-Code Template Number Signal processor checks the value of the pseudo-code
template to execute when the Control processor sends it.
Subcodes: Template number requested.
Likely Causes: Control processor software error.
Invalid Command Number Signal processor checks the value of the command issued by
the Control processor.
Subcodes: Command number issued.
Likely Causes: Control processor software error.
