PROM VERSION
18.1 EPROM mode
18.1.2 Programming/reading
EPROM mode can perform programming/reading to and from the built-in PROM with the same manner as
M5M27C101K. However, there is no device identification code. Accordingly, programming conditions must
be set carefully. Perform the programming to addresses 1400016 to 1FFFF16.
Table 18.1.3 lists the pin correspondence with M5M27C101K. Figure 18.1.1 shows the pin connections in
EPROM mode. Table 18.1.4 lists the built-in PROM states in EPROM mode.
