Instruction Size^* Function
EXTS
W/L
Rd (sign extension) → Rd
Extends byte data in the lower 8 bits of a 16-bit register to word data, or
extends word data in the lower 16 bits of a 32-bit register to longword data,
by extending the sign bit.
EXTU
W/L
Rd (zero extension) → Rd
Extends byte data in the lower 8 bits of a 16-bit register to word data, or
extends word data in the lower 16 bits of a 32-bit register to longword data,
by padding with zeros.
