The microcontrollers of the MB89910 series offer a memory space of 64 Kbytes for storing all of I/O, data, and

program areas. The I/O area is located the lowest address. The data area is provided immediately above the I/

O area. The data area can be divided into register, stack, and direct areas according to the application. The
