The tables list the functions of Auxiliary Area words and bits in order of their addresses. For a list of Auxiliary
Area words and bit by function, refer to SECTION 8 Memory Areas.
The Auxiliary Area consists of read-only words A000 to A447 and read/write words A448 to A959.
Read-only Words

Name
ON: A duplex verification error caused the
previous switch from duplex to simplex
operation.
ON: A duplex bus error caused the previ-
ous switch from duplex to simplex opera-
tion.
ON: An error during duplex initialization
caused the previous switch from duplex to
simplex operation and duplex operation
was never started.
ON: Changing the CPU Unit’s switch from
USE to NO USE caused the previous
switch from duplex to simplex operation.
ON: A CPU Unit error (WDT) caused the
previous switch from duplex to simplex
operation.
ON: Execution of an FALS instruction
caused the previous switch from duplex to
simplex operation.
ON: Exceeding the cycle time caused the
previous switch from duplex to simplex
operation.
ON: A program error caused the previous
switch from duplex to simplex operation.
ON: A fatal Inner Board error caused the
previous switch from duplex to simplex
operation. (Process-control CPU Units
only)
ON: A memory error caused the previous
switch from duplex to simplex operation.
