Section 14 Smart Card Interface
14.2.4
Bits 1 and 0 have different functions in smart card interface mode.
Bit
Initial value
Read/Write
Bits 7 to 2: Operate in the same way as for the normal SCI.
For details, see section 13.2.6, Serial Control Register (SCR).
Bits 1 and 0—Clock Enable (CKE1, CKE0): Setting enable or disable for the SCI clock
selection and 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.
