9. Cautions on Switching of SCK
If the function of the SCK
clock synchronization mode, the low level is output in a moment (1/2 of the system clock ø) at the
SCK
This momentary low level output can be avoided in either of the following two methods:
10. Setting in Subactive and Subsleep Modes
In subactive or subsleep mode, SCI3 can be used only when the ø
Set the SA1 bit in SYSCR2 to 1.

b. When switching the SCK

pin function switching.
When stopping signal transmission, clear the bits TE and RE in SCR3, and set the CKE1
bit to 1 and the CKE0 bit to 0 simultaneously with a single command.
In this case, use the COM bit in SMR set at 1. This means it cannot be used as an I/O port.
Also, to avoid intermediate potential from being applied to the SCK
connected to the SCK
other devices.
When stopping signal transmission,
(1) Clear the bits TE and RE in SCR3, and set the CKE1 bit to 1 and the CKE0 bit to 0
(2) Then, clear the COM bit in SMR to 0.
(3) Finally, clear the bits CKE1 and CKE0 in SCR3 to 0. Avoid intermediate potential
simultaneously with a single command.
