CONTROLLER AREA NETWORK (bxCAN)
CONTROLLER AREA NETWORK (Cont’d)
CAN 2.0B Active Core
The bxCAN module handles the transmission and
the reception of CAN messages fully autonomous-
ly. Standard identifiers (11-bit) and extended iden-
tifiers (29-bit) are fully supported by hardware.
Control, Status and Configuration Registers
The application uses these registers to:
– Configure CAN parameters, e.g.baud rate
– Request transmissions
– Handle receptions
– Manage interrupts
– Get diagnostic information

Tx Mailboxes
Three transmit mailboxes are provided to the soft-
ware for setting up messages. The transmission
Scheduler decides which mailbox has to be trans-
mitted first.
Acceptance Filters
The bxCAN provides eight scalable/configurable
identifier filter banks for selecting the incoming
messages the software needs and discarding the
others.
Receive FIFO
Two receive FIFOs are used by hardware to store
the incoming messages. Three complete messag-
es can be stored in each FIFO. The FIFOs are
managed completely by hardware.
