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.

14.3.1
The main features of the smart card interface are as follows.
• One frame consists of 8-bit data plus a parity bit.
• In transmission, a guard time of at least 2 etu (elementary time units: the time for transfer of
• If a parity error is detected during reception, a low error signal level is output for a1 etu period
• If an error signal is detected during transmission, the same data is transmitted automatically
• Only asynchronous communication is supported; there is no synchronous communication
14.3.2
Figure 14.2 shows a pin connection diagram for the smart card interface.
In communication with a smart card, since both transmission and reception are carried out on a
single data transmission line, the TxD pin and RxD pin should both be connected to this line. The
data transmission line should be pulled up to V
