CPU
The C868 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 10.67 MHz external crystal (giving a
40MHz CPU clock), 58% of the instructions execute in 300 ns.

rwh Carry Flag
Set/cleared by hardware after each instruction to
indicate an odd/even number of "one" bits in the
accumulator, i.e. even parity.
General Purpose Flag
Used by arithmetic instructions.
Register Bank select control bits
These bits are used to select one of the four register
banks.
General Purpose Flag
Used by instructions which execute BCD operations.
Used by arithmetic instructions.
