3.3
To modify or evaluate the SICOFI-4- C status, the contents of up to 6 configuration
registers CR0 .. CR7 may be transferred to or from the SICOFI-4- C. This is started by
a SOP-Command (status operation command).
RW
LSEL
Note: If only one configuration register requires modification, for example CR5, this can
