Section Introduction 4-1 4-1 Introduction Most data areas in the CPM2B can be accessed as bits or words. (The TR area can be accessed by bit address only and the DM area can be accessed by word address only.) The following diagram shows the structure of the IR area and the relationship between bit and word addresses.
Section I/O Allocation 4-2 IR words that are not allocated to inputs or outputs can be used as work words. Work Bits The work bits can be used freely within the program. They can only be used within the program, however, and not for direct external I/O. SR Area These bits mainly serve as flags for CPM2B operation or contain present and set values for various functions. SR 253 to SR 255 are read-only. Refer to 4-3 SR Area for details on the various bit functions.
Section I/O Allocation CPU Board I/O Allocation 4-2 CPU Board inputs are allocated input bits starting from IR 00000 and CPU Board outputs are allocated output bits starting from IR 01000. Input bits IR 00108 to IR 00111 are allocated to the CPU Board’s DIP switch inputs.
