29.3.2.9
The FADDRHI and FADDRLO registers are the Flash address registers.
All FADDRHI and FADDRLO bits are readable but are not writable. After an array write as part of a
command write sequence, the FADDR registers will contain the mapped MCU address written.
29.3.2.10 Flash Data Registers (FDATA)
The FDATAHI and FDATALO registers are the Flash data registers.
