12.10.7 Switching from SCK Pin Function to Port Pin Function:
When switching the SCK pin function to the output port function (high-level output) by making
the following settings while DDR = 1, DR = 1, C/A = 1, CKE1 = 0, CKE0 = 0, and TE = 1
(synchronous mode), low-level output occurs for one half-cycle.
1. End of serial data transmission
2. TE bit = 0
3. C/A bit = 0 ... switchover to port output
4. Occurrence of low-level output (see figure 12.43)
