Note: The VRFY input only selects read-only or read/write mode, and does not have any pin
associated with it on the M5M28F101.
Parallel I/O Mode
The parallel I/O mode is entered by making connections shown in Figures CC-2 and CC-3 and then turning
the VPPH power supply on. In this mode, the M30201 (flash memory version) operates in a manner similar
to the NOR flash memory M5M28F101 from Mitsubishi. Note, however, that there are some differences
with regard to the functions not available with the microcomputer (function of read device identification
code) and matters related to memory capacity.
Table CC-2 shows pin relationship between the M30201 and M5M28F101 in parallel I/O mode.

Type No.
Note 1: In CPU rewrite and standard serial I/O modes, the user ROM is the only erasable/programmable area.
Note 2: In parallel I/O mode, the area to be erased/programmed can be selected by the address A17 input.
The user ROM area is selected when this address input is high and the boot ROM area is selected
when this address input is low.
