Multiplexer Registers within E1300/E1406 A16 Address Space The Base Address When you are reading or writing to a multiplexer register, a hexadecimal or decimal register address is specified. This address consists of an A16 base address plus a register offset or register number. The A16 base address used in register-based programming depends on whether the A16 address space is located inside the E1300(01) Mainframe, E1405/06 Command Module, or elsewhere (e.g., embedded computer).
