Each F MC-16LX instruction code consists of 1 or 2 bytes. Therefore, the instruction
map consists of multiple pages. Table B.9-2 "Basic page map" to Table B.9-21 "XCHW

An instruction such as the NOP instruction that ends in one byte is completed within the basic
page. An instruction such as the MOVS instruction that requires two bytes recognizes the
existence of byte 2 when it references byte 1, and can check the following one byte by
referencing the map for byte 2. Figure B.9-2 "Correspondence between actual instruction code
and instruction map" shows the correspondence between an actual instruction code and
