Section 18 Smart Card Interface
Bits 3 to 0—These bits have the same function as in the ordinary SCI. See section 17, Serial
Communication Interface (SCI), for more information. The setting conditions for bit 2, the
transmit end bit (TEND), are changed as follows.
Bit 2: TEND
0
1
Note: etu: Elementary Time Unit (time for transfer of 1 bit)

18.3.1
The primary functions of the smart card interface are described below.
1. Each frame consists of 8-bit data and 1 parity bit.
2. During transmission, the card leaves a guard time of at least 2 etu (elementary time units: time
3. During reception, the card outputs an error signal low level for 1 etu after 10.5 etu has elapsed
4. During transmission, it automatically transmits the same data after allowing at least 2 etu from
5. Only start-stop type asynchronous communication functions are supported; no synchronous

Operation
Overview
Description
Transmission is in progress.
TEND is cleared to 0 when software reads TDRE after it has been set to 1, then
writes 0 in TDRE.
End of transmission.
TEND is set to 1 when:
•
•
•
•
the chip is reset or enters standby mode,
the TE bit in SCSCR is 0 and the FER/ERS bit is also 0,
the C/A bit in SCSMR is 0, and TDRE = 1 and FER/ERS = 0 (normal
transmission) 2.5 etu after a one-byte serial character is transmitted, or
the C/A bit in SCSMR is 1, and TDRE = 1 and FER/ERS = 0 (normal
transmission) 1.0 etu after a one-byte serial character is transmitted.
