Chapter 18 64 Kbyte Flash Module (S12FTS64KV4)
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
mass erase, any address within the Flash array is valid to start the command.
18.3.2.10 Flash Data Register (FDATA)
FDATAHI and FDATALO are the Flash data registers.
In normal modes, all FDATAHI and FDATALO bits read 0 and are not writable. In special modes, all
FDATAHI and FDATALO bits are readable and writable when writing to an address within the Flash
address range.
