8.5.1
The sequence of events for programming an internal
program memory location should be:
1.
2.
3.
4.
5.
6.
DS39616D-page 92
Read 64 bytes into RAM.
Update data values in RAM as necessary.
Load Table Pointer with address being erased.
Do the row erase procedure (see
“Flash Program Memory Erase
Load Table Pointer with the address of the first
byte being written.
Write the first 8 bytes into the holding registers
with auto-increment.
FLASH PROGRAM MEMORY WRITE
SEQUENCE
Sequence”).
Section 8.4.1
7.
8.
9.
10. Write 0AAh to EECON2.
11. Set the WR bit. This will begin the write cycle.
12. The CPU will stall for the duration of the write
13. Execute a NOP.
14. Re-enable interrupts.
15. Repeat Steps 6-14 seven times to write
16. Verify the memory (table read).
This procedure will require about 18 ms to update one
row of 64 bytes of memory. An example of the required
code is given in
Set the EECON1 register for the write operation
by doing the following:
• Set the EEPGD bit to point to program
• Clear the CFGS bit to access program
• Set the WREN bit to enable byte writes
Disable interrupts.
Write 55h to EECON2.
(about 2 ms using internal timer).
64 bytes.
