AT91SAM7X512/256/128 Preliminary
Synchronous Serial Controller (SSC)
SSC: Periodic Transmission Limitations in Master Mode
SSC: Transmitter Limitations in Slave Mode
SSC: Transmitter Limitations in Slave Mode
If the Least Significant Bit is sent first (MSBF = 0), the first TAG during the frame synchro is not
sent.
None.
If TK is programmed as output and TF is programmed as input, it is impossible to emit data
when the start of edge (rising or falling) of synchro has a Start Delay equal to zero.
None.
If TK is programmed as an input and TF is programmed as an output and requested to be set to
low/high during data emission, the Frame Synchro signal is generated one bit clock period after
the data start and one data bit is lost. This problem does not exist when generating a periodic
synchro.
The data need to be delayed for one bit clock period with an external assembly. In the following
schematic, TD, TK and NRST are AT91SAM7X signals, TXD is the delayed data to connect to
the device.
