Processor mode

The M37920S4CGP operates only in the microprocessor mode ex-

clusive for the external ROM. Be sure to fix the level at pin MD0 to

Vcc and the level at pin MD1 to Vss. Also, be sure to fix bits 1, 0 at

address 5E16 (the processor mode register 0) to “1” and “0”, respec-

tively.

Microprocessor mode

When the microcomputer starts its operation after reset with the level

at pin MD0 = Vcc level (5 V), the microcomputer is placed in the mi-

croprocessor mode.
