| ACCOFF | if AccBP is 0, the Acceptance Filter is not operational. All Rx messages on all CAN buses are ignored. |
| ACCBP | All Rx messages are accepted on enabled CAN controllers. Software must set this bit before modifying the contents of any of the registers described below, and before modifying the contents of Lookup Table RAM in any way other than setting or clearing Disable bits in Standard Identifier entries. When both this bit and AccOff are 0, the Acceptance filter operates to screen received CAN Identifiers. |
| EFCAN | FullCAN mode 0 (SOFTWARE_MUST_READ_A): Software must read all messages for all enabled IDs on all enabled CAN buses, from the receiving CAN controllers. 1 (THE_ACCEPTANCE_FILTE): The Acceptance Filter itself will take care of receiving and storing messages for selected Standard ID values on selected CAN buses. See Section 21.16 FullCAN mode on page 576. |
