4.6.2
Configuration bits may be programmed, a single byte at
a time, using the PROGW command. This command
specifies the configuration data and Configuration
register
programmed, any unimplemented or reserved bits
must be programmed with a ‘1’.
Four PROGW commands are required to program the
Configuration bits. A flowchart for Configuration bit
programming is shown in Figure 4-5.

PROGRAMMING METHODOLOGY
If the General Segment Code-Protect bit
(GCP) is programmed to ‘0’, code memory
is code-protected and can not be read.
Code memory must be verified before
enabling read protection. See Section 4.6.4
“Code-Protect Configuration Bits” for
more
Configuration bits.

4.6.3
After the Configuration bits are programmed, the
contents of memory should be verified to ensure that
the programming was successful. Verification requires
the Configuration bits to be read back and compared
against the copy held in the programmer’s buffer. The
READP command reads back the programmed
Configuration bits and verifies that the programming
was successful.
