S Z A P C          7 6 4 2 0

SAHF copies bits 7, 6, 4, 2, and 0 from the AH register into the Flags
register, replacing the previous values of the Sign, Zero, Auxiliary
Carry, Parity, and the Carry flags.

Notes:         The Overflow, Direction, Interrupt, and Trap flags
are not changed by this instruction.

This instruction is primarily used to provide upward
compatibility between the 8080/8085 family and the
8086 family.
