: Same functions as M5L27C256K
EPROM MODE
The M37477E8, M37478E8 feature an EPROM mode in addition
to its normal modes. When the RESET signal level is low (“L”), the
chip automatically enters the EPROM mode. Table 2 lists the cor-
respondence between pins and Figure 30 to 32 give the pin
connection in the EPROM mode. When in the EPROM mode,
ports P0, P11 to P17, P20 to P23, P3, P40, P41 and VREF are used
for the PROM (equivalent to the M5L27C256K). When in this
mode, the built-in PROM can be written to or read from using
these pins in the same way as with the M5L27C256K. The oscilla-
tor should be connected to the XIN and XOUT pins, or external
clock should be connected to the XIN pin.
