An example of the complete eight-word write sequence
is shown in Example 10-4. The initial address is loaded
into the EEADRH and EEADR register pair; the eight
words of data are loaded using indirect addressing.

;
; Disable interrupts (if using)
; See AN576
; Start of required write sequence:
; Write 55h

; Write 0AAh
; Set WR bit to begin write
; Required to transfer data to the buffer

; Enable interrupts (comment out if not using interrupts)
; Increment address
; Indicates when sixteen words have been programmed

; Exit on a match,
; Continue if more data needs to be written
Required Sequence
0x0F = 16 words
0x0B = 12 words (PIC16F884/883/882 only)
0x07 = 8 words
0x03 = 4 words(PIC16F884/883/882 only)
