access it. A failed status means that the EEPROM
chip may be defective.
Digital Signal Processor (DSP)
The DSP failure word in message 1100 indicates
the results of the DSP tests. A failed status
indicates that one or more of the DSP tests failed
and that the DSP chip may be defective.
RTC
The RTC failure word in message 1100 indicates
the results of a time rollover test of the RTC. A
failed status indicates that the RTC test failed and
that the RTC chip may be defective.
PORT 1 (host port) and PORT 2 (aux port) error and
received byte counts
There are no explicit tests for the two serial
communications ports. However, a count of bytes
received with error and a count of bytes received
without error for each port are maintained and
reported in Message 1100. These words provide
a measure of the reliability of the communications
interface. If the count of bytes received with error
is large, the interface may be defective or the port
configuration may be incorrect.
