Bits 6 to 0: These bits operate as in normal serial communication. For details see section 12.2.5,
Serial Mode Register (SMR).
13.2.4
The function of SCR bits 1 and 0 is modified in smart card interface mode.
Bits 7 to 2: These bits operate as in normal serial communication. For details see section 12.2.6,
Serial Control Register (SCR).
Bits 1 and 0—Clock Enable 1 and 0 (CKE1, CKE0): These bits select the SCI clock source and
enable or disable clock output from the SCK pin. In smart card interface mode, it is possible to
specify a fixed high level or fixed low level for the clock output, in addition to the usual switching
between enabling and disabling of the clock output.
