NOTES:
1 Selection between FlexCAN clock and XOSC clock is done via the CLK_SRC bit in the FlexCAN_0âs CTRL register.
2 Selection between FlexCAN clock and XOSC clock is done via the CLK_SRC bit in the FlexCAN_1âs CTRL register.
3 Selection between FlexRay clock and XOSC clock is done via the CLKSEL bit in the FlexRayâs FR_MCR register.
