Figure 16.12 shows an Initialization in Clock Synchronous Communication Mode. Set the TE bit in the SSER
register to 0 (disables transmit) and the RE bit to 0 (disables receive) before data transmit / receive as an
initialization.
When communication mode and format are changed, set the TE bit to 0 and the RE bit to 0 before changing.
Setting the RE bit to 0 does not change the contents of the RDRF and ORER flags, and the contents of the
SSRDR register.
