If (unsigned) rA < (unsigned) rB, then bltu transfers program control to the instruction at label. In the instruction encoding, the offset given by IMM16 is treated as a signed number of bytes relative to the instruction immediately following bltu. The two least-significant bits of IMM16 are always zero, because instruction addresses must be word-aligned.
Misaligned destination address
A = Register index of operand rA
B = Register index of operand rB
IMM16 = 16-bit signed immediate value
