The two CAN controllers in the LPC2926/2927/2929 have the pins listed below. The CAN
pins are combined with other functions on the port pins of the LPC2926/2927/2929.

The LPC2926/2927/2929 contain two LIN 2.0 master controllers. These can be used as
dedicated LIN 2.0 master controllers with additional support for sync break generation and
with hardware implementation of the LIN protocol according to spec 2.0.
Remark: Both LIN channels can be also configured as UART channels.
The key features are:

(SCL) and a Serial DAta line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or as a transmitter with
the capability to both receive and send information (such as memory). Transmitters and/or
