LPC11C12/C14

receivers can operate in either master or slave mode, depending on whether the chip has

to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be

controlled by more than one bus master connected to it.

7.10.1 Features

• The I2C-interface is a standard I2C-bus compliant interface with open-drain pins. The

I2C-bus interface also supports Fast-mode Plus with bit rates up to 1 Mbit/s.

• Easy to configure as master, slave, or master/slave.

• Programmable clocks allow versatile rate control.

• Bidirectional data transfer between masters and slaves.

• Multi-master bus (no central master).

• Arbitration between simultaneously transmitting masters without corruption of serial

data on the bus.

• Serial clock synchronization allows devices with different bit rates to communicate via

one serial bus.

• Serial clock synchronization can be used as a handshake mechanism to suspend and

resume serial transfer.

• The I2C-bus can be used for test and diagnostic purposes.

• The I2C-bus controller supports multiple address recognition and a bus monitor mode.

7.11 C_CAN controller

Controller Area Network (CAN) is the definition of a high performance communication

protocol for serial data communication. The C_CAN controller is designed to provide a full

implementation of the CAN protocol according to the CAN Specification Version 2.0B. The

C_CAN controller allows to build powerful local networks with low-cost multiplex wiring by

supporting distributed real-time control with a very high level of security.

On-chip C_CAN drivers provide an API for initialization and communication using CAN

and CANopen standards.

7.11.1 Features

• Conforms to protocol version 2.0 parts A and B.

• Supports bit rate of up to 1 Mbit/s.

• Supports 32 Message Objects.

• Each Message Object has its own identifier mask.

• Provides programmable FIFO mode (concatenation of Message Objects).

• Provides maskable interrupts.

• Supports Disabled Automatic Retransmission (DAR) mode for time-triggered CAN

applications.

• Provides programmable loop-back mode for self-test operation.

• The C_CAN API includes the following functions:

– C_CAN set-up and initialization

– C_CAN send and receive messages
