Figure 28-19. Flash Data Low Register (FDATALO)
All FDATAHI and FDATALO bits are readable but are not writable. 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.
