controller area network (CAN) module
The CAN module is a 16-bit peripheral. The accesses are split into the control/status registers and accesses
to the mailbox RAM.
CAN peripheral registers: The CPU can access the CAN peripheral registers only using 16-bit write accesses.
The CAN peripheral always presents full 16-bit data to the CPU bus during read cycles.
The CAN module is a full-CAN controller designed as a 16-bit peripheral module and supports the following
features:
CAN specification 2.0B (active)
Standard data and remote frames
Extended data and remote frames
Six mailboxes for objects of 0- to 8-byte data length
Two receive mailboxes, two transmit mailboxes
Two configurable transmit/receive mailboxes
Local acceptance mask registers for mailboxes 0 and 1 and mailboxes 2 and 3
Configurable standard or extended message identifier
Programmable global mask for objects 1 and 2 and one for object 3 and 4
Configurable standard or extended message identifier
Programmable bit rate
Programmable interrupt scheme
Readable error counters
Self-test mode
In this mode, the CAN module operates in a loop-back fashion, receiving its own transmitted message.
CAN memory map
Table 17 and Table 18 show the register and mailbox locations in the CAN module.
