EPROM MODE
The M37735EHBXXXFP 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 list the
correspondence between pins and Figure 4 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.
