Pulse Width Modulation Controller
Multimedia Card Interface
CAN Controller
• Each channel is user-configurable and contains:
• Two global registers that act on all three TC Channels
• 4 channels, one 16-bit counter per channel
• Common clock generator, providing thirteen different clocks
• Independent channel programming
• Two double-channel Multimedia Card Interfaces, allowing concurrent transfers with 2 cards
• Compatibility with MultiMediaCard Specification Version 3.11
• Compatibility with SD Memory Card Specification Version 1.1
• Compatibility with SDIO Specification Version V1.0.
• Cards clock rate up to Master Clock divided by 2
• Embedded power management to slow down clock rate when not used
• Each MCI has two slots, each supporting
• Support for stream, block and multi-block data read and write
• Fully compliant with 16-mailbox CAN 2.0A and 2.0B CAN Controllers
• Bit rates up to 1Mbit/s.
• Object-oriented mailboxes, each with the following properties:
– Delay Timing
– Pulse Width Modulation
– Up/down Capabilities
– Three external clock inputs
– Five internal clock inputs
– Two multi-purpose input/output signals
– Modulo n counter providing eleven clocks
– Two independent Linear Dividers working on modulo n counter outputs
– Independent Enable Disable commands
– Independent clock selection
– Independent period and duty cycle, with double bufferization
– Programmable selection of the output waveform polarity
– Programmable center or left aligned output waveform
– One slot for one MultiMediaCard bus (up to 30 cards) or
– One SD Memory Card
– CAN Specification 2.0 Part A or 2.0 Part B programmable for each message
– Object Configurable as receive (with overwrite or not) or transmit
– Local Tag and Mask Filters up to 29-bit Identifier/Channel
– 32 bits access to Data registers for each mailbox data object
– Uses a 16-bit time stamp on receive and transmit message
