Do not turn these bits ON and OFF in the program; manipulate them from the
SSS.
3-6-6 SYSMAC BUS Error Check Bits
Bits A00500 through A00507 can be turned ON to read out the error codes
(stored in words A470 through A477) for Masters numbered #0 through #7, re-
spectively. The Error Check Bits are turned OFF automatically after the informa-
tion has been read out. Refer to 3-6-39 SYSMAC BUS Error Flag for more de-
tails.
3-6-7 SSS Flags
Word A008 contains flags that indicate the status of commands and instructions
performed with the SSS.
Note During duplex operation, the status of the SSS Flags in the active CPU Unit will
not agree with the same flags in the standby CPU Unit.
Bit A00807 is turned ON when the Stop Monitor is used from the SSS, and is
turned OFF when it is completed.
Bit A00808 is turned ON when the execution time has been measured with
MARK(174) instructions with the SSS.
Bit A00809 is turned ON when the differentiate monitor condition has been es-
tablished with the SSS.
Bit A00810 is turned ON when the Stop Monitor operation has been completed
with the SSS.
Bit A00811 is turned ON when one of the trigger conditions has been established
during execution of a Data or Program Trace with the SSS.
Bit A00812 is turned ON upon when the sampling of a region of trace memory
has been completed during execution of a Data or Program Trace with the SSS.
Bit A00813 is turned ON when a Data or Program Trace is executed with the
SSS, and is turned OFF when it is completed.
The Trigger conditions are established when bit A00814 is turned ON by one of
trigger conditions of a Data or Program Trace of the SSS.
Bit A00815 is turned ON to start a Data Trace.
3-6-8 Start-up Time
Words A010 and A011 contain the start-up time, in BCD format, as shown in the
following table. The start-up time is updated every time the power is turned ON.
