AT91SAM9R64/RL64 Preliminary
Serial Synchronous Controller (SSC)
SSC: Transmitter Limitations in Slave Mode
SSC: Periodic Transmission Limitations in Master Mode
SSC: Unexpected RK clock cycle when RK outputs a clock during data transfer
SSC: Incorrect first RK clock cycle when RK outputs a clock during data transfer
If TK is programmed as output and TF is programmed as input, it is impossible to emit data
when start of edge (rising or falling) of synchro with a Start Delay equal to zero.
None.
If Last Significant Bit is sent first (MSBF = 0) the first TAG during the frame synchro is not sent.
None.
When the SSC receiver is used in the following configuration:
then, at the end of the data, the RK pin is set in high impedance which may be interpreted as an
unexpected clock cycle.
Enable the pull-up on RK pin.
When the SSC receiver is used in the following configuration:
• the internal clock divider is used (CKS =0 and DIV different from 0),
• RK pin set as output and provides the clock during data transfer (CKO=2)
• data sampled on RK falling edge (CKI =0)
• RX clock is divided clock (CKS =0 and DIV different from 0)
• RK pin set as output and provides the clock during data transfer (CKO=2)
• data sampled on RK falling edge (CKI =0)
