4.2.4.4 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.
4.2.4.5 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 user is required to check
that the previous flash operation has fully completed before
issuing a Byte-Verify. Byte-Verify command execution time
is short enough that there is no need to poll for command
completion and no interrupt is generated.
4.2.4.6 Prog-SB3, Prog-SB2, Prog-SB1
Prog-SB3, Prog-SB2, Prog-SB1 commands are used to
program the security bits (see Table 9-1). Completion of
any of these commands, the security options will be
updated immediately.
Security bits previously in un-programmed state can be
programmed by these commands. Prog-SB3, Prog-SB2
and Prog-SB1 commands should only reside in Block 1 or
external code memory.
