C504
Data Sheet
11
2000-05
CPU
The C504 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
are executed in 1.0
s (24 MHz: 500 ns, 40 MHz: 300 ns).
Special Function Register PSW (Address D0H)
Reset Value: 00
