Chapter 2 256 Kbyte Flash Module (FTS256K2V1)
All FDATAHI and FDATALO bits are readable but are not writable. After an array write as part of a
command write sequence, the FDATA registers will contain the data written. At the completion of a data
compress operation, the resulting 16-bit signature is stored in the FDATA registers. The data compression
signature is readable in the FDATA registers until a new command write sequence is started
