C515A
CPU
The C515A 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 18 MHz crystal, 58% of the instructions are executed in 666 ns
(24 MHz : 500 ns).
Special Function Register PSW (Address D0H)
Reset Value : 00H
Bit
Function
CY
Carry Flag
Used by arithmetic instruction.
AC
Auxiliary Carry Flag
Used by instructions which execute BCD operations.
F0
General Purpose Flag

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.
