Bits 14:8 – TDCO[6:0] Transmitter Delay Compensation Offset
Value Description
0x00 -
0x7F
Offset value defining the distance between the measured delay from CAN_TX to CAN_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 CAN_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.
