Function
Rd ÷ Rs
Performs signed division on data in two general
registers: either 16 bits ÷ 8 bits
remainder or 32 bits ÷ 16 bits
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
bits according to the result.
0 – Rd
Takes the two’s complement (arithmetic complement) of
data in a general register.
Rd (zero extension)
Extends the lower 8 bits of a 16-bit register to word size,
or the lower 16 bits of a 32-bit register to longword size,
by padding with zeros on the left.
Rd (sign extension)
Extends the lower 8 bits of a 16-bit register to word size,
or the lower 16 bits of a 32-bit register to longword size,
by extending the sign bit.
Tests memory contents, and sets the most significant bit
(bit 7) to 1.
