AFMR2 (CAN) Register Bit-Field Summary
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| AMIDH | 31:21 | rwNormal read/write | 0 | Standard Message ID Mask These bits are used for masking the Identifier in a Standard Frame. 1: Indicates the corresponding bit in Acceptance Mask ID Register is used when comparing the incoming message identifier. 0: Indicates the corresponding bit in Acceptance Mask ID Register is not used when comparing the incoming message identifier. |
| AMSRR | 20 | rwNormal read/write | 0 | Substitute Remote Transmission Request Mask This bit is used for masking the RTR bit in a Standard Frame. 1: Indicates the corresponding bit in Acceptance Mask ID Register is used when comparing the incoming message identifier. 0: Indicates the corresponding bit in Acceptance Mask ID Register is not used when comparing the incoming message identifier. |
| AMIDE | 19 | rwNormal read/write | 0 | Identifier Extension Mask Used for masking the IDE bit in CAN frames. 1: Indicates the corresponding bit in Acceptance Mask ID Register is used when comparing the incoming message identifier. 0: Indicates the corresponding bit in Acceptance Mask ID Register is not used when comparing the incoming message identifier. If AMIDE = 1 and the AIIDE bit in the corresponding Acceptance ID register is 0, this mask is applicable to only Standard frames. If AMIDE = 1 and the AIIDE bit in the corresponding Acceptance ID register is 1, this mask is applicable to only extended frames. If AMIDE = 0 this mask is applicable to Standard frame. |
| AMIDL | 18:1 | rwNormal read/write | 0 | Extended Message ID Mask These bits are used for masking the Identifier in an Extended Frame. 1: Indicates the corresponding bit in Acceptance Mask ID Register is used when comparing the incoming message identifier. 0: Indicates the corresponding bit in Acceptance Mask ID Register is not used when comparing the incoming message identifier. |
| AMRTR | 0 | rwNormal read/write | 0 | Remote Transmission Request Mask. This bit is used for masking the RTR bit in an Extended Frame. 1: Indicates the corresponding bit in Acceptance Mask ID Register is used when comparing the incoming message identifier. 0: Indicates the corresponding bit in Acceptance Mask ID Register is not used when comparing the incoming message identifier. |
