CPU
The C513AO is efficient both as a controller and as an arithmetic processor. It has extensive
facilities for binary and BCD arithmetic and excels in its bit-handling capabilities. Efficient use of
program memory results from an instruction set consisting of 44% one-byte, 41% two-byte, and
15% three-byte instructions. With a 16-MHz crystal, 58% of the instructions execute in 750 ns.
