• Manufacturer Part Number: HD6432621
• Description: (HD64F262x Series) 16-Bit Microcomputer
• Manufacturer: Hitachi

14.1
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.
14.1.1
Features of the Smart Card interface supported by the H8S/2626 Series and H8S/2623 Series 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
