GENERAL DESCRIPTION
Implements a fast, fully-functional, single-chip, 8bit microprocessor with the same instruction set as the Z80. The microcode-free design was developed for reuse in ASIC and FPGA implementations. It is strictly synchronous, with no internal tri-states and a synchronous reset.FEATURES
Programming features contain 208 bits of read/write memory that are accessible to the programmer. The internal registers include an accumulator and six 8-bit registers that can be paired as three 16-bit registers. In addition to general registers, a 16-bit stack-pointer, 16-bit program-counter, and two 16-bit index registers are provided.●
