14 / 48 page  PIC24FXXKAXXX DS39919A-page 14 Advance Information © 2008 Microchip Technology Inc. 3.7 Writing Data EEPROM Figure 3-9 illustrates the flow of programming the data EEPROM memory. The procedure is the same as writing code memory. The only difference is that only one word is programmed in each operation. When writing data EEPROM, one word is programmed during each operation. Working register, W0, is used as a temporary holding register for the data to be programmed. Table 3-6 provides the ICSP programming details for writing data EEPROM. FIGURE 3-9: PROGRAM DATA EEPROM MEMORY FLOW Note: The TBLPAG register is hard-coded to 0x7F (the upper byte address of all locations of data EEPROM). Start Write Sequence All locations done? No End Start Yes Load 2 Bytes to Write Buffer at <Addr> and Poll for WR bit to be Cleared LoopCount = 0 Configure Device for Writes LoopCount = LoopCount + 1 |
