16.4.7
In clock synchronous communication mode, data communications are performed via three lines:
clock line (SSCK), data input line (SSI), and data output line (SSO).
(1)
Figure 16.12 shows an example of the initial settings in clock synchronous communication mode.
Before data transfer, clear both the TE and RE bits in SSER to 0 to set the initial values.
Note: Before changing operating modes and communications formats, clear both the TE and RE

bits to 0. Although clearing the TE bit to 0 sets the TDRE bit to 1, clearing the RE bit to 0
does not change the values of the RDRF and ORER bits and SSRDR. Those bits retain the
previous values.
