Rd3 • K3 + K3 • R3 + R3 • Rd3
Set if there was a borrow from bit 3; cleared otherwise.
Rd7 • K7 • R7 + Rd7 • K7 • R7
Set if two’s complement overflow resulted from the operation; cleared otherwise.
R7
Set if MSB of the result is set; cleared otherwise.
R7 • R6 • R5 • R4 • R3 • R2 • R1 • R0
Set if the result is $00; cleared otherwise.
Rd7 • K7 + K7 • R7 + R7 • Rd7

R (Result) equals Rd after the operation.
Example:
subi r22,$11 ; Subtract $11 from r22 brne noteq ; Branch if r22<>$11 ... noteq: nop ; Branch destination (do nothing)
