2.3.2.8
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.
2.3.2.9
The FCTL register is the Flash control register.
All bits in the FCTL register are readable but are not writable.
The FCTL register is loaded from the Flash Configuration Field byte at $FF0E during the reset sequence,
indicated by F in
