REPORT STORE
The report store holds information concerning the success
or failure of the execution of the last instruction, and is
addressed by means of the CODENN, C0 and C1 lines as for
the instruction store The report store is addressed when the R/
WN line is low, the instruction store when the R/WN line is
high.
The report store comprises a Report word, a receive status
word (if applicable) and a transmit status word (if applicable).
The fourth location has no meaning and is not at anytime
addressed.

REPORT WORD
The report word gives the subsystem information as to the
type of error associated with the last transfer (the word will be
clear if no error occurred). The report word is formatted as
follows:
The Report word is written at the end of message
execution, after all retries have been exhausted and prior to
the IRQN line being set active This word indicates the health of
the terminal as well as information relating to the message
execution.
Transmitter Timeout Error
This bit will be set if a transmitter timeout error occurs while
the terminal is transmittting or if a self test on the transmitter
timeout mechanism fails. This will come into effect 800us after
the commencement of the Self Test. The setting of this bit will
also cause a subsystem interrupt to be generated.
This bit will be reset to logic zero if the terminal is reset.
Subsystem Handshake Failure
This bit will be set if the subsystem fails to acknowledge a
terminal request to transfer a data word in 0.75us for a
received data word or 13.5us for a transmit data word. If this
condition takes place while the terminal is transmitting the
transmission will be aborted. The setting of this bit will also
cause a subsystem interrupt to be generated..
This bit will be reset to logic zero if the terminal is reset.
Loop Test Failure
This bit will be set if the receiver circuitry detects an
absence of terminal transmission or a waveform encoding
error occurs while the terminal is transmitting. The seting of
this bit while the terminal is transmitting will cause the
transmission to be aborted and a subsystem interrupt to be
generated.
This bit will be reset to logic zero if the terminal is reset.
Programmed Halt
This bit will be set if the Interrupt Always flag of the
Instruction word has been selected.
This bit will be reset at the start of each new instruction
execution cycle.
Retry Used
This bit will be set if one or more message retries has been
attempted.
This bit will be reset at the start of each new instruction
execution cycle.
Word Count Low
This bit will be set if the terminal detects fewer valid data
words than specified by the Transmit Command word of the
Instruction set.
This bit will be set low at the start of each instruction
execution cycle or message retry.
Word County High
This bit will be set if the terminal detects more valid data
words than specified by the Transmit Command word of the
Instruction set.
This bit will be set low at the start of each instruction
execution cycle or message retry.
Command Error
This bit will be set if an error occurs in the Instruction set.
The setting of this bit will cause instruction execution to be
aborted and a subsystem interrupt to be generated.
This bit will be reset at the start of each new instruction
execution cycle.
