C505 / C505C
C505A / C505CA
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.
Special Function Register PSW (Address D0H)
Reset Value : 00H

RS0
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
P
Parity Flag
Set/cleared by hardware after each instruction to indicate an odd/even
number of "one" bits in the accumulator, i.e. even parity.
