Switching SCK Pin to Port Output Pin in Synchronous Mode
When the SCK pin is used as the serial clock output in synchronous mode, and is then switched to
its output port function at the end of transmission, a low level may be output for one half-cycle.
Half-cycle low-level output occurs when SCK is switched to its port function with the following
settings when DDR = 1, DR = 1, C/A = 1, CKE1 = 0, CKE0 = 0, and TE = 1.
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 13.23)
