M_CAN_FBTP field descriptions (continued)
Field Description
3–7
TDCO
Transceiver Delay Compensation Offset
NOTE: This field has Protected Write status.
0x00–0x1F Offset value defining the distance between the measured delay from M_CAN Tx to M_CAN
Rx and the secondary sample point. Valid values are 0 to 31 M_CAN clock periods
8
TDC
Transceiver Delay Compensation
NOTE: This field has Protected Write status.
0 Transceiver Delay Compensation disabled
1 Transceiver Delay Compensation enabled
9–10
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
11–15
FBRP
Fast Baud Rate Prescaler
(0x000–0x1F)— The value by which the oscillator frequency is divided for generating the bit time quanta.
The bit time is built up from a multiple of this quanta. Valid values for the Baud Rate Prescaler are 0 to 31.
The actual interpretation by the hardware of this value is such that one more than the value programmed
here is used.
NOTE: This field has Protected Write status.
16–19
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
20–23
FTSEG1
Fast time segment before sample point
(0x1–0xF)— Valid values are 1 to 15. The actual interpretation by the hardware of this value is such that
one more than the programmed value is used.
NOTE: This field has Protected Write status.
24
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
25–27
FTSEG2
Fast time segment after sample point
(0x0–0x7)— Valid values are 0 to 7. The actual interpretation by the hardware of this value is such that
one more than the programmed value is used.
NOTE: This field has Protected Write status.
28–29
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
30–31
FSJW
Fast (Re) Synchronization Jump Width
(0x0–0x3)— Valid values are 0 to 3. The actual interpretation by the hardware of this value is such that
one more than the value programmed here is used.
NOTE: This field has Protected Write status.
