MPC57444P CAN CLOCK

I found 5744P CAN CLOCK have two ways to configure,the first way is XOSC,and the second way is CAN_PLL_CLK. 

If I disabled the AUX CLock Selector2,the CPU will default to choose the XOSC for the CAN clock ? Thank you!

Hi,

yes, the CAN_CLK is generated from either the XOSC or divided PLL0_PHI clock (CAN_PLL_CLK). FlexCAN_CTRL1[CLK_SRC] selects whether CAN_PLL_CLK or XOSC clock drives the output of the multiplexer for the CAN_CLK.
