Figure 2-14. Flash Address Low Register (FADDRLO)
In normal modes, all FABHI and FABLO bits read 0 and are not writable. In special modes, the FABHI
and FABLO bits are readable and writable. For sector erase, the MCU address bits [9:0] are ignored. For
mass erase, any address within the Flash array is valid to start the command.
2.3.2.10 Flash Data Register (FDATA)
FDATAHI and FDATALO are the Flash data registers.
