Extension memory is configured and is used to hold RAM texts and RAM DBs.
Step 1: Hardware configuration
In this example, only 112 Kbytes of Flash EPROM are available as code/text memory
(on the plug-in chip); one block of memory is lost to configuration data (header),
because Flash EPROM can only be accessed in block mode.
For a PCD2.M110/M120 with hardware version < J, only 24 Kbytes of extension
memory (onboard memory) can be configured; previously, less base memory was
provided with these CPU types.
Step 2: Downloading the hardware configuration
Step 3: Modifying system settings
