Section 30 SIM Card Module (SIM)
The smart card interface supports IC cards (smart cards) conforming to the ISO/IEC 7816-3
(Identification Card) specification.
30.1 Features
• Communication functions
Asynchronous half-duplex transmission
Protocol selectable between T = 0 and T = 1 modes
Data length: 8 bits
Parity bit generation and check
Selectable character protection addition time
Selectable output clock cycles per etu
Transmission of error signal (parity error) in receive mode when T = 0
Detection of error signal and automatic character retransmission in transmit mode when T = 0
Selectable minimum character interval of 11 etus (N = 255) when T = 1 (etu: Elementary Time
Unit)
Selectable direct convention/inverse convention
Output clock can be fixed in high or low state
• Freely selectable bit rate by on-chip baud rate generator
• Four types of interrupt source
Transmit data empty, receive data full, transmit/receive error, transmit complete
• DMA transfer
Through DMA transfer requests for transmit data empty and receive data full, the direct
memory access controller (DMAC) can be started and used for data transfer.
• The time waiting for the operation when T = 0, and the time waiting for a character when T = 1
can be observed.
