The CIF can be used for asynchronous services, configuration and diagnosis.
For all commands, the parameter (BFM #1001 to #1066) must be set first. When the command code is written
to BFM #1000, the command is executed and BFM #1000 shows HFFFF (CIF busy). BFM #1000 to #1066
must not be changed until a positive or negative acknowledge is displayed in BFM #1000.
For details, refer to descriptions of each CIF command and the error code list of CIF.
