14 Initiating a Flash Row Write
Once a row of data has been downloaded into the device’s SRAM, the programming sequence
must be initiated to write the block of data to the Flash memory. See Table 14-1 for the op code and instructions for initiating a Flash row write.
Note: Certain PIC32 devices have available ECC memory. When the ECC
feature is used, the Flash memory must be programmed in groups of four 32-bit words
using four, 32-bit word alignment. If ECC is dynamically used, the programming
method determines when the feature is used. ECC is not enabled for words programmed
with the single word programming command. ECC is enabled for words programmed in
groups of four, either with the quad word or row programming commands. Failure to
adhere to these methods can result in ECC DED errors during run-time. Refer to the
specific device data sheet for details regarding ECC use and
configuration..
