2.3.3 Immediate Data Format
Byte (8 bit) immediate data resides in an instruction code. Immediate data accessed by the MOV,
ADD, and CMP/EQ instructions is sign-extended and handled in registers as longword data.
Immediate data accessed by the TST, AND, OR, and XOR instructions is zero-extended and
handled as longword data. Consequently, AND instructions with immediate data always clear the
upper 24 bits of the destination register.
Word or longword immediate data is not located in the instruction code, but instead is stored in a
memory table. An immediate data transfer instruction (MOV) accesses the memory table using the
PC relative addressing mode with displacement.
