These flags are refreshed every cycle while the SYSMAC LINK System is
operating.

SYSMAC LINK/SYSMAC NET Link System Service Time
AR 16 provides the time allocated to servicing operating level 0 of the SYS-
MAC LINK System and/or SYSMAC NET Link System during each cycle
when a SYSMAC LINK Unit and/or SYSMAC NET Link Unit is mounted to a
Rack.
AR 17 provides the time allocated to servicing operating level 1 of the SYS-
MAC LINK System and/or SYSMAC NET Link System during each cycle
when a SYSMAC LINK Unit and/or SYSMAC NET Link Unit is mounted to a
Rack.
These times are recorded in 4-digit BCD to tenths of a millisecond (000.0 ms
to 999.9 ms) and are refreshed every cycle.

Tracing Flags and Control Bits
AR 1812 through AR 1815 are used with trace operations, which are de-
scribed in
5-23 Data Tracing – TRSM(45)
. AR 1812 and AR 1813 are re-
freshed every cycle.
Sampling begins on the rising edge of the Sampling Start Bit, AR 1815. Ac-
tual tracing begins on the rising edge of the Trace Start Bit, AR 1814. The
Tracing Flag, AR 1813, turns ON then tracing has started. When tracing has
completed, the Tracing Flag turns OFF and the Trace Complete Flag, AR
1812, turns ON.

File Memory Flags and Control Bits
AR 19 through AR 21 are used with File Memory operations, which are de-
scribed in
5-24 File Memory Instructions
.
The following table describes the flags and reset bits available for FM opera-
tions. The actual use of these is described in more detail in
5-24 File Memory
Instructions
. AR 1903 through AR 1907 are refreshed every cycle when a
File Memory Unit is mounted.
