CPU
The C505 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 are executed in 375 ns (20MHz:
300 ns).
