_write_eedata_row(p, source);
Erase a page of FLASH memory. The length of a page is
_FLASH_PAGE words (1 word = 3 bytes = 2 PC address units.)

void _erase_flash(_prog_addressT dst);
dst
None.
None.
Erase a page of FLASH memory.
_erase_flash.c
Write a row of FLASH memory with 16-bit data. The length of a row is
_FLASH_ROW words. The upper byte of each destination word is filled
with 0xFF. Note that the row must be erased before any write can be
successful.
<libpic30.h>
void _write_flash16(_prog_addressT dst,
dst
*src
None.
None.
Write a row of FLASH memory with 16-bit data.
_write_flash16.c
Write a row of FLASH memory with 24-bit data. The length of a row is
_FLASH_ROW words. Note that the row must be erased before any write
can be successful.
<libpic30.h>
void _write_flash24(_prog_addressT dst,
