8.4 Operating modes
Introduction
Operating modes describe the states of the CPU. The following operating states are possible
via the mode selector:
● STARTUP
● RUN
● STOP
In these operating modes, the CPU can communicate, e.g. via the PN/IE interface.
The status LEDs on the front side of the CPU indicate the current operating mode.
