CPU
The C515C 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 6 MHz crystal,
58% of the instructions are executed in 1
s (10 MHz: 600 ns).

Register Bank select control bits
These bits are used to select one of the four register banks.
OV
Overflow Flag
Used by arithmetic instruction.
F1
General Purpose Flag
PParity Flag
Set/cleared by hardware after each instruction to indicate an
odd/even number of “one” bits in the accumulator, i.e. even parity.
