Figure 12.24 Operation when Switching from SCK Pin Function to Port Pin Function
Sample Procedure for Avoiding 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.
