Step 7: Repeat Steps 5 and 6 to erase the second page of executive memory. The W1 Pointer should be
Step 8: Initialize TBLPAG and NVMCON to write stored diagnostic and calibration as single words. Initialize W1
Step 9: Perform write of a single word of calibration data and initiate single-word write cycle.
Step 10: Repeat this step to poll the WR bit (bit 15 of NVMCON) until it is cleared by the hardware.
Step 11: Repeat steps 9-10 seven more times to program the remainder of the Diagnostic and Calibration Words
Step 12: Initialize the NVMCON to program 64 instruction words.
Step 13: Initialize TBLPAG and the Write Pointer (W7).
Step 14: Load W0:W5 with the next four words of packed programming executive code and initialize W6 for
