Clocked Serial Interface (CSIB)
Note
Caution
1.
In single transmission or single transmission/reception mode, the INTCBnT
signal is not generated. When communication is complete, the INTCBnR
signal is generated.
2.
The processing of steps (3) and (4) can be set simultaneously.
In case the CSIB interface is operating in
•
single transmit/reception mode (CBnCTL0.CBnTMS = 0)
•
communication type 2 respectively type 4 (CBnCTL1.CBnDAP = 1)
pay attention to following effect:
In case the next transmit should be initiated immediately after the occurrence
of the reception completion interrupt INTCBnR any write to the CBnTX register
is ignored as long as the communication status flag is still reflecting an ongoing
communication (CBnTSF = 1). Thus the new transmission will not be started.
For transmitting data continuously use one of the following options:
•
Use continuous transfer mode (CBnCTL0.CBnTMS = 1).
•
If single transfer mode (CBnCTL0.CBnTMS = 0) should be used,
CBnSTR.CBnTSF = 0 needs to be verified before writing data to the
CBnTX register.
