Function
Rd
Performs signed division on data in two general registers: either 16 bits
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 the 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.
@ERd – 0, 1
Tests memory contents, and sets the most significant bit (bit 7) to 1.
