Motorola Bus (M Bus) Interface
11.6 M-Bus Registers
11.6.1 M-Bus Address Register
General Release Specification
NOTE:
Address:
Five different registers are used in the M-bus interface. The internal
configuration of these registers is discussed in the following paragraphs.
The register addresses show only the low-order address bits (for
example ABL3–ABL0). The registers can be placed anywhere in the
device memory map by generating an appropriate module select signal
in the map logic.
A block diagram of the M-bus system is shown in
Bit 1–Bit 7
