s PROGRAMMING TO THE EPROM ON THE MB89P817A
In EPROM mode, the MB89P817A functions equivalent to the MBM27C256A. This allows the OTPROM to be
programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by
using the dedicated socket adapter.
Writing Procedure
(1) Set the EPROM programmer to the MBM27C256A.
(2) Load program data into the EPROM programmer at 0007H to 7FFFH (note that addresses 8007H to FFFFH
while operating as operating mode assign to 0007H to 7FFFH in EPROM mode).
Load option data into addresses 0000H to 0006H of the EPROM programmer. (For information about each
corresponding option, see “
OTPROM Option Bit Map.”)
(3) Program with the EPROM programmer.
