26.5.1
Figure 26.10 shows Initialization in 4-Wire Bus Communication Mode. Before the data transit/receive
operation, set the TE bit in the SSER register to 0 (transmission disabled), the RE bit in the SSER register to 0
(reception disabled), and initialize the synchronous serial communication unit.
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 settings of flags RDRF and ORER or the contents of the SSRDR
register.
