13.2.4
Bits 1 and 0 of SCR have a different function in smart card interface mode.
Bits 7 to 2—Operate in the same way as for the normal SCI.
For details, see section 12.2.6, Serial Control Register (SCR).
Bits 1 and 0—Clock Enable (CKE1, CKE0): Selects the clock source, and enables or disables
clock output from the SCK pin.
In smart card interface mode, it is possible to switch between enabling and disabling of the normal
clock output, and specify a fixed high level or fixed low level for the clock output.
