15.2.4
In Smart Card interface mode, the function of bits 1 and 0 of SCR changes when bit 7 of the serial mode register (SMR) is
set to 1.
Bits 7 to 2—Operate in the same way as for the normal SCI.
For details, see section 14.2.6, Serial Control Register (SCR).
Bits 1 and 0—Clock Enable 1 and 0 (CKE1, CKE0): These bits are used to select the SCI clock source and enable or
disable clock output from the SCK pin.
In Smart Card interface mode, in addition to the normal switching between clock output enabling and disabling, the clock
output can be specified as to be fixed high or low.
