Format
BSR
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 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.

long disp;
if ((d&0x800)==0) disp=(0x00000FFF & (long) d);
else disp=(0xFFFFF000 | (long) d);
PR=PC+Is_32bit_Inst(PR+2);
PC=PC+(disp<<1);
