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, P1
1
to P1
7
, P2
0
to P2
3
, P3, P4
0
, P4
1
and V
REF
are used
for the PROM (equivalent to the M5L27C256). 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 oscillator should
be connected to the X
IN
and X
OUT
pins, or external clock should
be connected to the X
IN
pin.
