dsPIC30F Flash Programming Specification
11.9
Writing Data EEPROM
The procedure for writing data EEPROM is very similar
to the procedure for writing code memory, except that
fewer words are programmed in each operation. When
writing data EEPROM, one row of data EEPROM is
programmed at a time. Each row consists of sixteen
16-bit data words. Since fewer words are programmed
during each operation, only working registers W0:W3
are used as temporary holding registers for the data to
be programmed.
Table 11-9 shows the ICSP programming details for
writing data EEPROM. Note that a different NVMCON
value is required to write to data EEPROM, and that the
TBLPAG register is hard-coded to 0x7F (the upper byte
address of all locations of data EEPROM).
