CPU
The SAB-C502 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 12 MHz crystal, 58 % of the instructions execute in 1.0
μ
s
(18 MHz : 667 ns).
