12.0 PROGRAMMING THE
PROGRAMMING EXECUTIVE
TO MEMORY
12.1
Overview
If it is determined that the programming executive does
not reside in executive memory (as described in
Memory”), it must be programmed into executive
memory using ICSP and the techniques described in
Storing the programming executive to executive
memory is similar to normal programming of code
memory. The executive memory must first be erased,
and then the programming executive must be
programmed 32 words at a time. This control flow is
summarized in Table 12-1.

Step 7: Load W0:W5 with the next 4 words of packed programming executive code and initialize W6 for
programming. Programming starts from the base of executive memory (0x800000) using W6 as a read
pointer and W7 as a write pointer.
