Section 13 Serial Communication Interface
Switching SCK Pin to Port Output Pin Function 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 outpu
4. Occurrence of low-level output (see figure 13.23)
