CY
This bit is set when the last arithmetic operation results in a carry (addition) or a borrow
(subtraction). It is cleared to 0 by all other arithmetic operations.
This bit is set when the last arithmetic operation results in a carry into (addition) or a
borrow from (subtraction) the high order nibble. It is cleared to 0 by all other arithmetic
operations.
This is a bit-addressable, general purpose flag for use under software control.
These bits select which register bank is used during register accesses.
Note: Any instruction which changes the RS1-RS0 bits must not be immediately followed
by the “MOV Rn, A” instruction.
This bit is set to 1 under the following circumstances:
This is a bit-addressable, general purpose flag for use under software control.
(Read only)
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.
CY: Carry Flag.
AC: Auxiliary Carry Flag.
F0: User Flag 0.
OV: Overflow Flag.
F1: User Flag 1.
PARITY: Parity Flag.
The OV bit is cleared to 0 by the ADD, ADDC, SUBB, MUL, and DIV instructions in all
other cases.
A DIV instruction causes a divide-by-zero condition.
An ADD, ADDC, or SUBB instruction causes a sign-change overflow.
A MUL instruction results in an overflow (result is greater than 255).
