Section 18 SIM Card Module (SIM)
The smart card interface supports IC cards (smart cards) conforming to the ISO/IEC 7816-3
(Identification Card) specification.
18.1 Features
The SIM has the following 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
Extra guard time selectable
Output clock cycles per etu selectable
Transmission of error signal (parity error) in receiver mode with T = 0
Detection of error signal and automatic character repetition in transmitter mode with T = 0
Minimum character interval 11 etu selectable for T = 1
Direct convention/inverse convention selectable
Output clock fixable in high or low state
• Baud rate freely specifiable with internal baud rate generator
• Four types of interrupt factor
Transmit data empty, receive data full, transmit/receive error, transmission complete
• DMA transfer
The direct memory access controller (DMAC) can be activated to be used for data transfer
using a transmit data empty DMA transfer request or a receive data full DMA transfer request.
The receiver can observe the interval between the start of two successive characters.
[Legend] etu (elementary time unit): Time for 1-bit transfer
