• Manufacturer Part Number: h8s-2646
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

14.1
SCI supports an IC card (Smart Card) interface conforming to ISO/IEC 7816-3 (Identification
Card) as a serial communication interface extension function.
Switching between the normal serial communication interface and the Smart Card interface is
carried out by means of a register setting.
14.1.1
Features of the Smart Card interface supported by the H8S/2646 Group are as follows.
• Asynchronous mode
• On-chip baud rate generator allows any bit rate to be selected
• Three interrupt sources
 Data length: 8 bits
 Parity bit generation and checking
 Transmission of error signal (parity error) in receive mode
 Error signal detection and automatic data retransmission in transmit mode
 Direct convention and inverse convention both supported
 Three interrupt sources (transmit data empty, receive data full, and transmit/receive error)
 The transmit data empty interrupt and receive data full interrupt can activate the data
that can issue requests independently
transfer controller (DTC) to execute data transfer
