4.2.3.4 Byte-Program
The Byte-Program command programs data into a single
byte. The address is determined by the contents of SFAH
and SFAL. The data byte is in SFDT.
4.2.3.5 Byte-Verify
The Byte-Verify command allows the user to verify that the
device has correctly performed an Erase or Program com-
mand. Byte-Verify command returns the data byte in SFDT
if the command is successful. The previous flash operation
has to be fully completed before a Byte-Verify command
can be issued.
4.2.3.6 Secure-Page0, Secure-Page1, Secure-
Page2, Secure-Page3, and Secure-Page4
Secure-Page0, Secure-Page1, Secure-Page2, Secure-
Page3, and Secure-Page4 commands are used to pro-
gram the page security bits. Upon completion of any of
these commands, the page security options will be
updated immediately.
Page security bits previously in un-programmed state can
be programmed by these commands. The factory setting
for these bits is all “1”s which indicates the pages are not
security locked.
