PROGRAMMING THE
PROGRAMMING EXECUTIVE
TO MEMORY
6.1
Overview
If it is determined that the programming executive is not
present in executive memory (as described in
Programming Executive”), it must be programmed
into executive memory using ICSP, as described in
Storing the programming executive to executive
memory is similar to normal programming of code
memory. Namely, the executive memory must first be
erased, and then the programming executive must be
programmed 64 words at a time. This control flow is
summarized in Table 6-1.
Note:
The
programming
executive
must
always
be
erased
before
it
is
programmed, as described in Table 6-1.

complete.

NOP
Clock out contents of VISI register. Repeat instruction until the WR bit is clear.
Step 4: Repeat Step 3 to erase all pages of executive memory (incrementing the page erase pointer, i.e., W1 pointer
should be incremented by 0x400 to point to the second page).
Step 5: Initialize the NVMCON to program 64 instruction words.
