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.
4.2.4.7 Prog-SC0
Prog-SC0 command is used to program the SC0 bit. This
command only changes the SC0 bit and has no effect on
BSEL bit until after a reset cycle.
SC0 bit previously in un-programmed state can be pro-
grammed by this command. The Prog-SC0 command
should reside only in Block 1 or external code memory.
4.2.4.8 Enable-Clock-Double
Enable-Clock-Double command is used to make the MCU
run at 6 clocks per machine cycle. The standard (default) is
12 clocks per machine cycle (i.e. clock double command
disabled).
