3.10.5. BLTS: Relative Branch if Signed Less Than

Encoding (format 12, first word at lower address):

1 1 0 0 1 0 0 s₂ s₁ s₀ a₂ a₁ a₀ b₂ b₁ b₀

0 0 0 s₉ s₈ s₇ s₆ s₅ s₄ s₃ a₅ a₄ a₃ b₅ b₄ b₃

Notes:

The comparison between R_a and R_b is a signed comparison, where the contents of each register is treated as a 2's-complement signed number.
Remember that the program counter is a word address, so the offset is the number of words by which to adjust the PC.
Branching to a non-existent location will trigger a bus error exception.
