 Two multi-purpose input/output signals
 Two global registers that act on all three TC channels
10.12 Pulse Width Modulation Controller
 Four channels, one 16-bit counter per channel
 Common clock generator, providing thirteen different clocks
 One Modulo n counter providing eleven clocks
 Two independent linear dividers working on modulo n counter outputs
 Independent channel programming
 Independent enable/disable commands
 Independent clock selection
 Independent period and duty cycle, with double buffering
 Programmable selection of the output waveform polarity
 Programmable center or left aligned output waveform
10.13 USB Device Port
 USB V2.0 full-speed compliant,12 Mbits per second
 Embedded USB V2.0 full-speed transceiver
 Embedded 1352-byte dual-port RAM for endpoints
 Six endpoints
 Endpoint 0: 8 bytes
 Endpoint 1 and 2: 64 bytes ping-pong
 Endpoint 3: 64 bytes
 Endpoint 4 and 5: 256 bytes ping-pong
 Ping-pong Mode (two memory banks) for bulk endpoints
 Suspend/resume logic
10.14 CAN Controller
• Fully compliant with CAN 2.0A and 2.0B
• Bit rates up to 1Mbit/s
• Eight object oriented mailboxes each with the following properties:
 CAN Specification 2.0 Part A or 2.0 Part B Programmable for each Message
 Object configurable to receive (with overwrite or not) or transmit
 Local tag and mask filters up to 29-bit identifier/channel
 32-bit access to data registers for each mailbox data object
 Uses a 16-bit time stamp on receive and transmit message
 Hardware concatenation of ID unmasked bitfields to speedup family ID processing
