Technical Reference Manual 002-29852 Rev. *B
2.3.9.6.7 CANFD_CH_NBTP
Description:
Nominal Bit Timing & Prescaler Register
Address:
0x4052001C
Offset:
0x1C
Retention:
Retained
IsDeepSleep:
No
Comment:
Protected Write. With a CAN clock (m_can_cclk) of 8 MHz, the reset value of 0x06000A03
configures the M_CAN for a bit rate of 500 Kbit/s.

Description
0:6 NTSEG2 RW R 3 Nominal Time segment after sample point
0x01-0x7F Valid values are 1 to 127. The actual
interpretation by the hardware of this value is
such that one more than the programmed value is
used.
8:15 NTSEG1 RW R 10 Nominal Time segment before sample point
0x01-0xFF Valid values are 1 to 255. The actual
interpretation by the hardware of this value is
such that one more than the programmed value is
used.
16:24 NBRP RW R 0 Nominal Bit Rate Prescaler
0x000-0x1FFThe 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 Bit
Rate Prescaler are 0 to 511. The actual interpretation
by the hardware of this value is
such that one more than the value programmed here is
used.
25:31 NSJW RW R 3 Nominal (Re)Synchronization Jump Width
0x00-0x7F Valid values are 0 to 127. The actual
interpretation by the hardware of this value is
such that one more than the value programmed here is
used.
