Chapter 27 512 Kbyte Flash Module (S12XFTX512K4V2)
The FCTL register is loaded from the Flash Configuration Field byte at global address 0x7F_FF0E during
the reset sequence, indicated by F in
27.3.2.9
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.
27.3.2.10 Flash Data Registers (FDATA)
The FDATAHI and FDATALO registers are the Flash data registers.
