The controller receives two clocks from the PMC clock controller. These clocks are programmed by the CRL register module.
- CANFDx_REF_CLK reference clocks
- LPD_LSBUS_CLK, see the CRL LPD_LSBUS_CTRL register
Clock frequency guidelines are included in the I/O Peripheral Clock Frequency Requirements section.
The LPD clock controller provides a reference clock to each controller.
- CAN0_REF_CLK reference clock ( CAN0_REF_CTRL register)
- CAN1_REF_CLK reference clock ( CAN1_REF_CTRL register)
