Figure 4.3.3 shows how to connect two Am29LV008B (flash memory). In 16-bit bus mode,the BHE/WRH
pin functions as BHE. When connecting 8-bit flash memory chips to the 16-bit bus, make sure the
microcomputer's WRL pin is connected to the WR pins on both flash memory chips, and that data is
written to the flash memory in units of 16 bits beginning with an even address.
