Step 1: Exit Reset vector and erase executive memory.
Step 2: Initialize the NVMCON to erase executive memory.
Step 3: Initialize Erase Pointers to first page of executive and then initiate the erase cycle.
Step 4: Repeat this step to poll the WR bit (bit 15 of NVMCON) until it is cleared by the hardware.
Step 5: Repeat Steps 3 and 4 to erase the second page of executive memory. The W1 Pointer should be
Step 6: Initialize the NVMCON to program 64 instruction words.
Step 7: Initialize TBLPAG and the Write Pointer (W7).

Programming Executive”), it must be programmed
into executive memory using ICSP, as described in
Section 3.0 “Device Programming – ICSP”.
Storing the programming executive to executive
memory is similar to normal programming of code
memory. Namely, the executive memory must be
erased, and then the programming executive must be
programmed, 64 words at a time. This control flow is
summarized in Table 5-5.
