EPROM MODE
The M37470E4/E8, M37471E4/E8 feature an EPROM mode in ad-
dition to its normal modes. When the RESET signal level is low
(“L”), the chip automatically enters the EPROM mode. Table 2 lists
the correspondence between pins and Figure 30 to 32 give the pin
connection in the EPROM mode. When in the EPROM mode,
ports P0, P11–P17, P20–P23, P3, P40, P41, VREF are used for the
PROM (equivalent to the M5L27256). 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 M5L27256. The oscillator should be con-
nected to the XIN and XOUT pins, or external clock should be
connected to the XIN pin.
