• Manufacturer Part Number: HD6412332
• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family/H8S/2300 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

15.1
The 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.
15.1.1
Features of the smart card interface supported by the chip is as follows.
• Asynchronous mode
• Built-in 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 and receive-data-full interrupts can activate the DMA controller
that can issue requests independently
(DMAC) or data transfer controller (DTC) to execute data transfer
