Section 13 Serial Communication Interface
Switching from SCK Pin Function to Port Pin Function:
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)

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/A = 1, CKE1 = 0,
CKE0 = 0, and TE = 1 (synchronous mode), low-level output occurs for one half-cycle.
