eZ8™ CPU Core Z8 Encore!® Microcontrollers
●About This Manual
■Zilog recommends that you read and understand all the chapters and instructions provided in this manual before setting up and using the product. This manual is designed to be used as a reference guide to important data.
●Architectural Overview
■Zilog's eZ8 CPU is the latest 8-bit central processing unit (CPU) designed to meet the continuing demand for faster and more code-effi-cient microcontrollers. The eZ8 CPU executes a superset of the original Z8 instruction set. The features of the eZ8 CPU include:
▲Direct register-to-register architecture, which allows each register to function as an accumulator to improve execution time and decrease the amount of required program memory
▲A software stack that allows much greater depth in subroutine calls and interrupts than hardware stacks
▲Compatibility with the Z8 assembly instruction set.
▲An expanded internal register file that allows access of up to 4 KB.
▲New instructions that improve execution efficiency for code devel-oped using higher-level programming languages, including C.
▲Pipelined instruction fetch and execution
