Bit7
CY: Carry Flag.
This bit is set when the last arithmetic operation resulted in a carry (addition) or a borrow
(subtraction). It is cleared to 0 by all other arithmetic operations.
AC: Auxiliary Carry Flag
This bit is set when the last arithmetic operation resulted in a carry into (addition) or a borrow
from (subtraction) the high order nibble. It is cleared to 0 by all other arithmetic operations.
F0: User Flag 0.
This is a bit-addressable, general purpose flag for use under software control.
RS1-RS0: Register Bank Select.
These bits select which register bank is used during register accesses.
OV: Overflow Flag.
This bit is set to 1 under the following circumstances:
The OV bit is cleared to 0 by the ADD, ADDC, SUBB, MUL, and DIV instructions in all 
F1: User Flag 1.
This is a bit-addressable, general purpose flag for use under software control.
PARITY: Parity Flag.
This bit is set to 1 if the sum of the eight bits in the accumulator is odd and cleared if the sum
is even.
other cases.
• An ADD, ADDC, or SUBB instruction causes a sign-change overflow.
• A MUL instruction results in an overflow (result is greater than 255).
• A DIV instruction causes a divide-by-zero condition.
