The following instructions cannot be placed in interrupt tasks. Any attempt to
execute one of these instructions in an interrupt task will cause the ER Flag to
turn ON and the instruction will not be executed.The following instructions can
be used if an interrupt task is being used as an extra task.

The operation of the following instructions is unpredictable in an interrupt task:
TIMER: TIM and TIMX((550), HIGH-SPEED TIMER: TIMH(015) and
TIMHX(551), ONE-MS TIMER: TMHH(540) and TMHHX(552), ACCUMULA-
TIVE TIMER: TTIM(087) and TTIMX(555), MULTIPLE OUTPUT TIMER:
MTIM(543) and MTIMX(554), LONG TIMER: TIML(542) and TIMLX(553),
TIMER WAIT: TIMW(813) and TIMWX(816), HIGH-SPEED TIMER WAIT:
TMHW(815) and TMHWX(817), PID CONTROL: PID(190), FAILURE POINT
DETECTION: FPD(269), and CHANGE SERIAL PORT SETUP: STUP(237).
The following instructions cannot be used in the power OFF interrupt task
(they will not be executed even if they are used and the Error Flag will not turn
ON):
READ DATA FILE: FREAD(700), WRITE DATA FILE: FWRIT(701), NET-
WORK SEND: SEND(090), NETWORK RECEIVE: RECV(098), DELIVER
COMMAND: CMND(490), PROTOCOL MACRO: PMCR(260).
The following flag work only for normal cyclic tasks. They do not work for extra
cyclic tasks.
A Task Flag is turned ON when a cyclic task in READY status and is turned
OFF when the task is in Disabled (INI) or in Standby (WAIT) status. Task num-
bers 00 to 31 correspond to Task Flags TK00 to TK31.
