• Problem in Operation: When DDR and DR are set to 1, SCI clock output is used in clocked
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 14.38)
synchronous mode, and the SCK pin is changed to the port pin while transmission is ended,
port output is enabled after low-level output occurs for one half-cycle.
When switching the SCK pin to the port pin by making the following settings while DDR = 1,
DR = 1, C/A = 1, CKE1 = 0, CKE0 = 0, and TE = 1, low-level output occurs for one half-
cycle.
