9 / 34 page  PRELIMINARY Notice: This is not a final specification. Some parametric limits are subject to change. 9 MITSUBISHI MICROCOMPUTERS M37735EHLXXXHP PROM VERSION OF M37735MHLXXXHP EPROM MODE The M37735EHLXXXHP features an EPROM mode in addition to its _____ normal modes. When the RESET signal level is “L”, the chip automatically enters the EPROM mode. Table 2 lists the correspondence between pins and Figure 5 shows the pin connections in the EPROM mode. The EPROM mode is the 1M mode for the EPROM that is equivalent to the M5M27C101K. When in the EPROM mode, ports P0, P1, P2, P30, P50, P51, P52, CNVSS and BYTE are used for the EPROM (equivalent to the M5M27C101K). When in this mode, the built-in PROM can be programmed or read from using these pins in the same way as with the M5M27C101K. This chip does not have Device Identifier Mode, so that set the corresponding program algorithm. The program area should specify address 0100016 – 1FFFF16. Connect the clock which is either ceramic resonator or external clock to XIN pin and XOUT pin. Table 2.
