The Z380™ offers a continuing growth path for present Z80-or Z180-based designs, while maintaining Z80® CPU and Z180® MPU object-code compatibility. The Z380™ MPU enhancements include an improved 280 CPU, expanded 4-Gbyte space and flexible bus interface timing. An enhanced version of the Z80 CPU is key to the Z380 MPU. The basic addressing modes of the Z80 microprocessor have been augmented as follows: Stack Pointer Relative loads and stores, 16-bit and 24-bit indexed offsets, and more flexible Indirect Register add...
