Step 5: Load the lower instruction word to the W5 register and the upper instruction byte to the W6 register.
Step 6: Write the program memory low word and the executive memory upper byte into the write latch and increment
Step 7: Initiate the write cycle.
Step 8: Wait for the word write operation to complete and make sure the WR bit is clear.
Step 9: Repeat steps 5-8 to write the remaining executive memory words.
