AF_Mask_Reg_n (CANFD) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
AMID | 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 m4essage 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. 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 both Standard and Extended frames. |
AMID_EXT | 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 |
