29.3.2.7
The FCMD register is the Flash command register.
All CMDB bits are readable and writable during a command write sequence while bit 7 reads 0 and is not
writable.
29.3.2.8
The FCTL register is the Flash control register.
All bits in the FCTL register are readable but are not writable.
The FCTL NV bits are loaded from the Flash nonvolatile byte located at global address 0x7F_FF0E during
the reset sequence, indicated by F in
