13.9.8
Some serial communication interface registers are assigned to the same address as other registers.
Register selection is performed by means of the IICE bit in the serial control register (SCRX). For
details on register addresses, see section 24, List of Registers.

Figure 13.42 Operation when Switching from SCK Pin Function to Port Pin Function
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
