R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-0 BMXPFMSZ<31:0>: Program Flash Memory (PFM) Size bits
Static value that indicates the size of the PFM in bytes:
0x00010000 = device has 64 KB Flash
0x00020000 = device has 128 KB Flash
0x00040000 = device has 256 KB Flash
