Description: Branches to the subroutine procedure at a specified address. The PC value is stored
in the PR, and the program branches to an address specified by PC + displacement However, in
this case it is used for address calculation. The PC is the address 4 bytes after this instruction. The
12-bit displacement is sign-extended and doubled. Consequently, the relative interval from the
branch destination is –4096 to +4094 bytes. If the displacement is too short to reach the branch
destination, the JSR instruction must be used instead. With JSR, the destination address must be
transferred to a register by using the MOV instruction. This BSR instruction and the RTS
instruction are used together for a subroutine procedure call.
Note: Since this is a delayed branch instruction, the instruction after BSR is executed before
Operation:

branching. No interrupts and address errors are accepted between this instruction and the
next instruction. If the next instruction is a branch instruction, it is acknowledged as an
illegal slot instruction.
