Single wire protocol master interface (SWPMI)

The Single wire protocol master interface (SWPMI) is the master interface corresponding to

the Contactless Frontend (CLF) defined in the ETSI TS 102 613 technical specification. The

main features are:

•

full-duplex communication mode

•

automatic SWP bus state management (active, suspend, resume)

•

configurable bitrate up to 2 Mbit/s

•

automatic SOF, EOF and CRC handling

SWPMI can be served by the DMA controller.

3.31

Controller area network (CAN)

The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It

can receive and transmit standard frames with 11-bit identifiers as well as extended frames

with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and

14 scalable filter banks.
