• Each mode setting is determined based on the mode vector fetch after INIT negate. (For details about
setting the modes, see Section "3.8.2 Mode Settings".)
• For the MB91V350A, with the memory map of the MB91355A/F355A/353A/F353A/F357B, the 512K bytes
area of the internal ROM, and with the memory map of the MB91F356B, the 256K bytes area of the internal
ROM, is the emulation RAM. In addition, internal RAM(Instruction) is extended from 8K bytes to16K bytes.
• The available internal RAM area is restricted as soon as a reset is cleared. If the available area setting
would be rewritten, include at least one NOP instruction immediately after that processing.
