Internal Output Numbers

Memory is available as an internal output area in the CPU module. There are three areas: bit dedicated area (R), word
dedicated area (WR), and bit/word shared area (M/WM).

Internal outputs R, WR and DR are completely separate areas. Bit-based operations cannot be performed in the WR.

WR/DR area
DR11
•
Because internal outputs M, WM and DM share the same area, bit-based operations are allowed.
