  Block Diagram and Operational
  Overview
  The PCIe-Mini -CAN board is engineered
  around the NXP LPC2387 microcontroller.
  This highly integrated 32 bits microcontroller
  based on the ARM7TDMI-S processor, has a
  very low power consumption and features 512 kB
  of on-chip high-speed flash memory.
  It incorporates several communications
  ports, specifically a USB full-speed
  Device/Host/OTG Controller with 4 kB of
  endpoint RAM, and two Controller Area
  Network (CAN) channels.
  The device controller enables 12 Mbit/s data
  exchange with a USB host controller. It
  consists of a register interface, serial
  interface engine, endpoint buffer memory,
  and a DMA controller. The serial interface
  engine decodes the USB data stream and
  writes data to the appropriate endpoint
  buffer. The status of a completed USB
  transfer or error condition is indicated via
  status registers.
  An interrupt is also generated if enabled.
  When enabled, the DMA controller transfers
  data between the endpoint buffer and the
  USB RAM.
  The Controller Area Network (CAN) is
  a serial communications protocol which
  efficiently supports distributed real-time
  control with a very high level of security.
  Its domain of application ranges from highspeed networks to low cost multiplex wiring.
