Normally, programming is performed in the HALT mode.
T3H operation mode control by programmer is not allowed.
RUN T3H executes user program cyclically. (RUN mode)
It is the normal switch position under operation.
Even in the RUN mode, program changes are possible. However, saving into the
EEPROM is available only in the HALT mode.
T3H operation mode control by programmer is possible.
P-RUN T3H executes user program cyclically. (RUN mode)
User program and the leading 4 k words of D register (D0000 to D4095) are write-
protected.
T3H operation mode control by programmer is possible.
Note) In case of T3, even in P-RUN, data writing into D0000 to D4095 by instruction
