Section 17 Smart Card Interface
17.1 Overview
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.
17.1.1 Features
Features of the Smart Card interface supported by the H8S/2633 Group are as follows.
• Asynchronous mode
⎯ 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
• On-chip baud rate generator allows any bit rate to be selected
• Three interrupt sources
⎯ Three interrupt sources (transmit data empty, receive data full, and transmit/receive error)
that can issue requests independently
⎯ The transmit data empty interrupt and receive data full interrupt can activate the DMA
controller (DMAC)
*
or data transfer controller (DTC)
*
to execute data transfer
Note: * DMAC and DTC functions are not available in the H8S/2695.
