25.4.1
Figure 25.4 shows Initialization in Clock Synchronous Communication Mode. To initialize, set the TE bit in the
SSER register to 0 (transmit disabled) and the RE bit to 0 (receive disabled) before data transmission or
reception.
Set the TE bit to 0 and the RE bit to 0 before changing the communication mode or format.
Setting the RE bit to 0 does not change the contents of flags RDRF and ORER or the contents of the SSRDR
register.
