Section 13 Serial Communication Interface
Sample Procedure for Preventing Low-Level Output
As this sample procedure temporarily places the SCK pin in the input state, the SCK/port pin
should be pulled up beforehand with an external circuit.
With DDR = 1, DR = 1, C/A = 1, CKE1 = 0, CKE0 = 0, and TE = 1, make the following settings
in the order shown.
1. End of serial data transmission
2. TE bit = 0
3. CKE1 bit = 1
4. C/A bit = 0 ... switchover to port output
5. CKE1 bit = 0
