Bits 14:8 – TDCO[6:0] Transmitter Delay Compensation Offset
| Value | Description |
|---|---|
| 0x00 - 0x7F | Offset value defining the distance between the measured delay from CANx_TX to CANx_RX and the secondary sample point. Valid values are 0 to 127 mtq. |
Bits 6:0 – TDCF[6:0] Transmitter Delay Compensation Filter Window Length
| Value | Description |
|---|---|
| 0x00 - 0x7F | Defines the minimum value for the SSP position, dominant edges on CANx_RX that would result in an earlier SSP position are ignored for transmitter delay measurement. The feature is enabled when TDCF is configured to a value greater than TDCO. Valid values are 0 to 127 mtq. |
