SFR Definition 18.1. CAN0DATL: CAN Data Access Register Low Byte
CAN0DATL: CAN Data Access Register Low Byte.
The CAN0DAT Registers are used to read/write register values and data to and from the
CAN Registers pointed to with the index number in the CAN0ADR Register.
The CAN0ADR Register is used to point the [CAN0DATH:CAN0DATL] to a desired CAN
Register. The desired CAN Register’s index number is moved into CAN0ADR. The
CAN0DAT Register can then read/write to and from the CAN Register.
CAN0ADR: CAN Address Index Register.
The CAN0ADR Register is used to point the [CAN0DATH:CAN0DATL] to a desired CAN
Register. The desired CAN Register’s index number is moved into CAN0ADR. The
CAN0DAT Register can then read/write to and from the CAN Register.
Note: When the value of CAN0ADR is 0x08-0x12 and 0x20-0x2A (IF1 and IF2 registers),
this register will autoincrement by 1 upon a write to CAN0DATL. See
“18.2.6. CAN0ADR Autoincrement Feature” on page
All CAN registers’ functions/definitions are listed and described in the Bosch CAN
User’s Guide.
