Background
The μPD768 is the single-chip implementation of the μCOM-1600 series, following the earlier two-chip μCOM-16 (μPD755/μPD756) from 1974. It has 93 basic instructions, each consisting of 1 to 3 16-bit words. The memory space of 1 Mbyte (512K words) is byte-addressable, and the I/O address space is 2048 bytes. The processor includes 14 general-purpose registers.
