The Application ID Word is stored at address 0x8007F0
in executive code memory. To read this memory
location, you must 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. The
corresponding control and instruction codes that must
be serially transmitted to the device to perform this
operation are shown in
TABLE 4-1:

Step 1: Exit the Reset vector.
Step 2: Initialize TBLPAG and the read pointer (W0) for TBLRD instruction.
Step 3: Output the VISI register using the REGOUT command.

After the programmer has clocked out the Application
ID Word, it must be inspected. If the application ID has
the value listed in
sion”, the programming executive is resident in mem-
ory and the device can be programmed using the
mechanism described in
gramming – Enhanced
cation ID has any other value, the programming
executive is not resident in memory; it must be loaded
to memory before the device can be programmed. The
procedure for loading the programming executive to
memory is described in
