17. Smart Card Interface
Bit 2—Transmit End (TEND): The setting conditions for the TEND flag are as follows.
Bit 2: TEND
0
1
Note: etu: Elementary time unit (time for transfer of 1 bit)

17.3.1
The main functions 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 unit: the time for transfer of one
• If a parity error is detected during reception, a low error signal level is output for a 1-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
