Switching from SCK Pin Function to Port Pin Function:
1. End of serial data transmission
2. TE bit = 0
3. C/
4. Occurrence of low-level output (see figure 13-27)

Figure 13-27 Operation when Switching from SCK Pin Function to Port Pin Function
Problem in Operation: 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/
CKE0 = 0, and TE = 1 (synchronous mode), low-level output occurs for one half-cycle.
