3.9.1.3 FlexCAN Clocking
3.9.1.3.1 Clocking Options
The FlexCAN module has a register bit CANCTRL[CLK_SRC] that selects between
clocking the FlexCAN from the internal bus clock or the input clock (EXTAL).
3.9.1.3.2 Clock Gating
The clock to each CAN module can be gated on and off using the SCGCn[CANx] bits.
These bits are cleared after any reset, which disables the clock to the corresponding
module. The appropriate clock enable bit should be set by software at the beginning of
the FlexCAN initialization routine to enable the module clock before attempting to
initialize any of the FlexCAN registers.
3.9.1.4 FlexCAN Interrupts
The FlexCAN has multiple sources of interrupt requests. However, some of these sources
are OR'd together to generate a single interrupt request. See below for the mapping of the
individual interrupt sources to the interrupt request:
3.9.1.5 FlexCAN Operation in Low Power Modes
The FlexCAN module is operational in VLPR and VLPW modes. With the 2 MHz bus
clock, the fastest supported FlexCAN transfer rate is 256 kbps. The bit timing parameters
in the module must be adjusted for the new frequency, but full functionality is possible.
