Step 8: Load W0:W5 with the next four words of packed programming executive code and initialize W6 for
Step 9: Set the Read Pointer (W6) and load the (next four write) latches.
Step 10: Repeat Steps 8 and 9, sixteen times, to load the write latches for the 64 instructions.
Step 11: Initiate the programming cycle.
Step 12: Repeat this step to poll the WR bit (bit 15 of NVMCON) until it is cleared by the hardware.
Step 13: Reset the device internal PC.
Step 14: Repeat Steps 8 through 13 until all 16 rows of executive memory have been programmed.
