There are a few changes to the format for immediate operands. Usually (possibly always) the high bit of the opcode is 1 for instructions with immediate operands. The D bit is replaced with an X (extension) bit. If the operands are 8-bit (W=0), then the X bit is ignored. If the operands are not 8-bit and X=0, then the immediate value is the same size as the operand size. If X=1, then the immediate is an 8-bit number which is sign-extended to the current operand size. Next, the REG field is replaced with an opcode extension, which will be different depending on the instruction in use. Finally, the immediate value is added to the end of the instruction, in little endian.
