User manual
The CAN controller in available on parts LPC2458 and LPC2460/68/70/78.
The CAN1/2 peripherals are configured using the following registers:
Controller Area Network (CAN) is the definition of a high performance communication
protocol for serial data communication. The CAN Controller is designed to provide a full
implementation of the CAN-Protocol according to the CAN Specification Version 2.0B.
Microcontrollers with this on-chip CAN controller are used to build powerful local networks
by supporting distributed real-time control with a very high level of security. The
applications are automotive, industrial environments, and high speed networks as well as
low cost multiplex wiring. The result is a strongly reduced wiring harness and enhanced
diagnostic and supervisory capabilities.
The CAN block is intended to support multiple CAN buses simultaneously, allowing the
device to be used as a gateway, switch, or router among a number of CAN buses in
various applications.
The CAN module consists of two elements: the controller and the Acceptance Filter. All
registers and the RAM are accessed as 32 bit words.
1. Power: In the PCONP register
2. Peripheral clock: In the PCLK_SEL0 register
3. Wakeup: Use the INTWAKE register
4. Pins: Select CAN1/2 pins and pin modes in registers PINSELn and PINMODEn (see
5. Interrupts: CAN interrupts are enabled using the CAN1/2IER registers
6. CAN controller initialization: see CANMOD register
