Register 10: Flash Write Buffer n (FWBn), offset 0x100 - 0x17C
These 32 registers hold the contents of the data to be written into the Flash memory on a buffered
Flash memory write operation. The offset selects one of the 32-bit registers. Only FWBn registers
that have been updated since the preceding buffered Flash memory write operation are written into
the Flash memory, so it is not necessary to write the entire bank of registers in order to write 1 or
2 words. The FWBn registers are written into the Flash memory with the FWB0 register corresponding
to the address contained in FMA. FWB1 is written to the address FMA+0x4 etc. Note that only data
bits that are 0 result in the Flash memory being modified. A data bit that is 1 leaves the content of
the Flash memory bit at its previous value.
