6.14.2.1 Pin description
6.14.2 LIN
The global acceptance filter provides look-up of received identifiers - called acceptance
filtering in CAN terminology - for all the CAN controllers. It includes a CAN ID look-up table
memory, in which software maintains one to five sections of identifiers. The CAN ID
look-up table memory is 2 kB large (512 words, each of 32 bits). It can contain up to 1024
standard frame identifiers or 512 extended frame identifiers or a mixture of both types. It is
also possible to define identifier groups for standard and extended message formats.
The two CAN controllers in the LPC2939 have the pins listed below. The CAN pins are
combined with other functions on the port pins of the LPC2939.
pins (x runs from 0 to 1).
Table 20.
The LPC2939 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:
