1 Memory map
To provide compatibility with ETS the operating system does a memory translation from bus
addresses to the internal addresses of the microcontroller. That means that for example the
start of the address table for the ETS is 0x0116 and in reality it is 0x8116 in the
microcontroller.
The following memory map tables show respectively the real memory addresses in the
microcontroller, the addresses which are used on the bus to access them, the type and for
what they are used.
