19.4.1 Read/Program/Erase
Table 19.4.2 lists the built-in PROM state in 256K mode and each mode is described bellow.
(1) Read
(2) Program (Write)
(3) Erase (Possible only in EPROM version)

Program
When pins CE and
of the built-in PROM can be output from data I/O pins and read.
When pins CE and
When pin
becomes possible.
Input an address to address input pins and supply data to be programmed to data I/O pins in 8-bit
parallel. In this condition, when pin CE is set to “L” level, the data is programmed at the specified
address, input address, into the built-in PROM.
The contents of the built-in PROM is erased by exposing the glass window on top of the package
to an ultraviolet light which has a wave length of 2537 Angstrom. The light must be 15 J/cm
