Input CLK for CAN on LPC5536

[ja_lpc]

Currently working on LPC5536uC for one product.

Through the Zephyr LPC5536 was getting configured to internal 96MHZ FRO.

But with the help of clock and pin tool on MCUXpress IDE I made changes to use the external clk via PLL and drive the main clock to 150MHz.

I see in the config tool that by default the CANCLKDIV value is 1 and hence CAN will endup getting fed with 150MHz in my case.

But for a 1Mbps on CAN, how much should be the CAN clock so that I can set the divider accordingly?

Hello @ja_lpc 

You can choose clock source for CAN, then use CANCLKDIV to get Baud rate. About detail recommend refer to CAN demo under SDK, and

config tool.

Hello @ja_lpc 

You can directly config baud rate on configuration tool as below:

Would this mean, we don't have to adjust the input frequency?

Hello @ja_lpc 

" adjust the input frequency?"

->> Please describe it more detail.
