Description: Reads the T bit and conditionally branches. If T = 0, it branches after executing the
next instruction. If T = 1, BF/S executes the next instruction. The branch destination is 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 8-bit displacement is sign-extended and doubled.
Consequently, the relative interval from the branch destination is –256 to +254 bytes. If the
displacement is too short to reach the branch destination, use BF with the BRA instruction or the
like.
Note: Since this is a delay branch instruction, the instruction immediately following is executed

before the branch. No interrupts and address errors are accepted between this instruction
and the next instruction. When the instruction immediately following is a branch
instruction, it is recognized as an illegal slot instruction. When branching, this is a two-
cycle instruction; when not branching, one cycle.
