Function
Rd ÷ Rs
Performs unsigned division on data in two general registers: either
16 bits ÷ 8 bits
16-bit quotient and 16-bit remainder.
Rd ÷ Rs
Performs signed division on data in two general registers: either
16 bits ÷ 8 bits
16-bit quotient and 16-bit remainder.
Rd – Rs, Rd – #IMM
Compares data in a general register with data in another general register or
with immediate data, and sets CCR according to the result.
0 – Rd
Takes the two’s complement (arithmetic complement) of data in a general
register.
Rd (sign extension)
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.
Rd (zero extension)
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.
