* Permissible memory submodules ( Section 2.3.2)
** FW 0 is reserved for the logical program counter.
FW 2 to FW 198 (F 2.0 to F 199.7) permissible for user program.
FW 200 to FW 254 (F 200.0 to F 255.7) are only permissible in blocks as
scratch flags. Scratch flags must be defined, set or reset at the start of
block execution and also after conditional or unconditional block
calls. This avoids data exchange with other blocks.
