Revision A2
Program Operation
This operation is used to program data to the flash EEPROM and the option bits. Programming is
initiated when V
PP
reaches V
CP
(12.5V) level,
CE
is set to low, and
OE
is set to high.
Program Verify Operation
All data must be checked after programming. This operation should be performed after each byte is
programmed, and it will ensure a substantial program margin.
