Figure 66. Example of 8-bit Synchronous Transmit Operation
Figure 67. Example of 8-bit Synchronous Receive Operation
In the 9-bit shift mode, the SSI is able to handle the MCL protocol (described below). It
always operates as an MCL master device, i.e., SC is always generated and output by
the SSI. Both the MCL start and stop conditions are automatically generated whenever
the SSI is activated or deactivated by the SIR-bit. In accordance with the MCL protocol,
the output data is always changed in the clock low phase and shifted in on the high
phase.
