the full MMC bus protocol, defined by the MMC Defini-
tion Group’s specification v.2.11. The controller can
also implement the SPI interface to the cards.
INTERFACE DESCRIPTION AND MMC OVERVIEW

• Power supply: VDD and VSS
• Data Transfer: MMCCMD, MMCDATA
• Clock: MMCLK.
MULTIMEDIACARD ADAPTER
Card specific functions, serves as the bus master for the
MultiMediacard Bus and implements the standard inter-
face to the MultiMediaCard Cards (card initialization,
CRC generation and validation, command/response
transactions, etc.).
Smart Card Interface (SCI)
Card reader. The SCI can autonomously control data
transfer to and from the smart card. Transmit and
receive data FIFOs are provided to reduce the required
interaction between the CPU core and the peripheral.
SCI FEATURES
• Supports asynchronous T0 and T1 transmission
• Supports clock rate conversion factor F = 372, with
• Eight-character-deep buffered Tx and Rx paths
• Direct interrupts for Tx and Rx FIFO level monitoring
• Interrupt status register
• Hardware-initiated card deactivation sequence on
• Software-initiated card deactivation sequence on
• Limited support for synchronous Smart Cards via
PROGRAMMABLE PARAMETERS
• Smart Card clock frequency
• Communication baud rate
• Protocol convention
• Card activation/deactivation time

• Check for maximum time of receipt of first character
• Check for maximum time allowed between characters
• Character guard time
• Block guard time
• Transmit/receive character retry.
