One UART adapted to suit Smart Card interface
needs, for asynchronous SC as defined by ISO
7816-3; it includes SC clock generation.
Two Serial Peripheral Interfaces (SPI) allow full
duplex, synchronous communications with
external devices, master or slave operation,
max baud rate: 8Mb/s. One SPI may be used as
Multimedia Card interface.
Two I2C Interfaces provide multi-master and
slave functions, support normal and fast I2C
mode (400KHz), 7/10 bit addressing modes.
One I2C Interface is multiplexed with one SPI,
so either 2xSPI+1xI2C or 1xSPI+2xI2C may be
