5.4.1
The user can program one row of program Flash
memory at a time. To do this, it is necessary to erase
the 8-row erase page that contains the desired row.
The general process is as follows:
1.
2.
3.
EXAMPLE 5-1:
DS70287C-page 76
; Set up NVMCON for block erase operation
; Init pointer to row to be ERASED
Read
(512 instructions) and store it in data RAM.
Update the program data in RAM with the
desired new data.
Erase the block (see Example 5-1):
a)
b)
c)
d)
e)
Set the NVMOP bits (NVMCON<3:0>) to
‘0010’ to configure for block erase. Set the
ERASE
(NVMCON<14>) bits.
Write the starting address of the page to be
erased into the TBLPAG and W registers.
Write 0x55 to NVMKEY.
Write 0xAA to NVMKEY.
Set the WR bit (NVMCON<15>). The erase
cycle begins and the CPU stalls for the dura-
tion of the erase cycle. When the erase is
done, the WR bit is cleared automatically.

6.
For protection against accidental operations, the write
initiate sequence for NVMKEY must be used to allow
any erase or program operation to proceed. After the
programming command has been executed, the user
must wait for the programming time until programming
is complete. The two instructions following the start of
the programming sequence should be NOPs, as shown
in Example 5-3.
Write the first 64 instructions from data RAM into
the program memory buffers (see Example 5-2).
Write the program block to Flash memory:
a)
b)
c)
d)
Repeat steps 4 and 5 using the next available 64
instructions from the block in data RAM by incre-
menting
512 instructions are written back to Flash memory.
Set the NVMOP bits to ‘0001’ to configure
for row programming. Clear the ERASE bit
and set the WREN bit.
Write 0x55 to NVMKEY.
Write 0xAA to NVMKEY.
Set the WR bit. The programming cycle
begins and the CPU stalls for the duration of
the write cycle. When the write to Flash mem-
ory is done, the WR bit is cleared
automatically.
