3.4
To modify or evaluate the SICOFI-4 status, the contents of up to four configuration
registers CR1, CR2, CR3 and CR4 may be transferred to or from the SICOFI-4. This is
started by a SOP-Command (status operation command).

RW
PWRUP
LSEL
All other codes are reserved for future use!
It is possible to program each Configuration register separately, just by putting only one
byte into the FIFO of the upstream master device (e.g. EPIC), and aborting after
transmission of one (or n) byte.
