19.2. CAN Registers
CAN registers are classified as follows:
1. CAN Controller Protocol Registers: CAN control, interrupt, error control, bus status, test
2. Message Object Interface Registers: Used to configure 32 Message Objects, send and
3. Message Handler Registers: These read only registers are used to provide information to
4. C8051 MCU Special Function Registers (SFR): Five registers located in the C8051 MCU
19.2.1. CAN Controller Protocol Registers
The CAN Control Protocol Registers are used to configure the CAN controller, process interrupts, monitor
bus status, and place the controller in test modes. The CAN controller protocol registers are accessible
using C8051 MCU SFRs by an indexed method, and some can be accessed directly by addressing the
SFRs in the C8051 SFR map for convenience.
The registers are: CAN Control Register (CAN0CN), CAN Status Register (CAN0STA), CAN Test Register
(CAN0TST), Error Counter Register, Bit Timing Register, and the Baud Rate Prescaler (BRP) Extension
Register. CAN0STA, CAN0CN, and CAN0TST can be accessed via C8051 MCU SFRs. All others are
accessed indirectly using the CAN address indexed method via CAN0ADR, CAN0DATH, and CAN0DATL.
Please refer to the Bosch CAN User’s Guide for information on the function and use of the CAN
Control Protocol Registers.
19.2.2. Message Object Interface Registers
There are two sets of Message Object Interface Registers used to configure the 32 Message Objects that
transmit and receive data to and from the CAN bus. Message objects can be configured for transmit or
receive, and are assigned arbitration message identifiers for acceptance filtering by all CAN nodes.
Message Objects are stored in Message RAM, and are accessed and configured using the Message
Object Interface Registers. These registers are accessed via the C8051’s CAN0ADR and CAN0DAT regis-
ters using the indirect indexed address method.
Please refer to the Bosch CAN User’s Guide for information on the function and use of the Mes-
sage Object Interface Registers.
19.2.3. Message Handler Registers
The Message Handler Registers are read only registers. Their flags can be read via the indexed access
method with CAN0ADR, CAN0DATH, and CAN0DATL. The message handler registers provide interrupt,
error, transmit/receive requests, and new data information.

modes.
receive data to and from Message Objects. The C8051 MCU accesses the CAN message
RAM via the Message Object Interface Registers. Upon writing a message object number
to an IF1 or IF2 Command Request Register, the contents of the associated Interface
Registers (IF1 or IF2) will be transferred to or from the message object in CAN RAM.

Pending, New Data Flags) and Interrupts Pending (which Message Objects have caused
an interrupt or status interrupt condition).

Indexed indirect access to all CAN registers.
