*1: The ROM area is an external area depending on the mode.
The MB89T623, MB89T625, MB89V623, and MB89V625 cannot use internal ROM.
*2: Since addresses 8000
MB89PV620 and MB89627.
*3: The MB89PV620 is the piggyback/evaluation product for the MB89628R, MB89629R, and MB89P629. However, the
MB89PV620 has an internal RAM size of 1 Kbyte only.
When using development tools, the memory can be simulated using the RAM on the tools. However, the RAM is insufficient
when used in piggyback operation. Also note that some tools such as the MB2120 series cannot be used due to mapping
restrictions.
