BSR instruction onto the system stack. The program counter contains the address of
the instruction word plus two. Program execution then continues at location (PC) +
displacement. The displacement is a twos complement integer that represents the
relative distance in bytes from the current program counter to the destination program
counter. If the 8-bit displacement field in the instruction word is zero, a 16-bit
displacement (the word immediately following the instruction) is used. If the 8-bit
displacement field in the instruction word is all ones ($FF), the 32-bit displacement
(long word immediately following the instruction) is used.
