RESTART_BUFFER
; Load TBLPTR with the base address
; of the memory block, minus 1
; enable write to memory
; enable Erase operation
; disable interrupts
; write 55h
; write 0AAh
; start erase (CPU stall)
; re-enable interrupts
; Need to write 16 blocks of 64 to write
; one erase block of 1024
; point to buffer
; read the new data from I2C, SPI,
; PSP, USART, etc.
; number of bytes in holding register
; get low byte of buffer data
; present data to table latch
; write data, perform a short write
; to internal TBLWT holding register.
; loop until buffers are full
; enable write to memory
; disable interrupts
; write 55h
; write 0AAh
; start program (CPU stall)
; re-enable interrupts
; disable write to memory
; done with one write cycle
; if not done replacing the erase block
