To verify the code memory, read the code memory
space and compare it with the copy held in the
programmer’s buffer. To verify the data EEPROM and
Configuration registers, follow the similar procedure.
Figure 3-10 illustrates the verify process flowchart.
Memory reads occur 1 byte at a time, hence 2 bytes
must be read to compare with the word in the
programmer’s buffer. Refer to Section 3.9 “Reading
Code Memory” for implementation details of reading
code memory. On the same lines, the data EEPROM
and Configuration registers can be verified.

immediately after writing if code protection
is enabled. Since Configuration registers
include the device code protection bit, the
device will not be readable or verifiable if a
device Reset occurs after the code-protect
bits are set (value = 0).

The Application ID Word is stored in address 8005BEh
in the executive code memory. To read this memory
location, use the SIX control code to move this program
memory location to the VISI register. Then, the
REGOUT control code must be used to clock the
contents of the VISI register out of the device.
Table 3-12 provides the corresponding control and
instruction codes that must be serially transmitted to
the device to perform this operation.
After the programmer has clocked out the Application
ID Word, it must be inspected. If the Application ID has
the value, BBh, the programming executive resides in
the memory and the device can be programmed using
the mechanism described in Section 4.0 “Device
Programming – Enhanced ICSP”. However, if the
Application ID has any other value, the programming
executive does not reside in the memory; it must be
loaded to memory before the device can be
programmed.
Programming Executive to Memory” describes the
procedure for loading the programming executive to
memory.
