I have a LPCXpresso with the LPC11C24, but I have changed the Oscillator to 20MHz to run the Chip at 50MHz. Now I want to use the C_CAN Module (Baudrate 50k) and I have Problems to select the correct Register values.
What is the max. frequency (or recommended frequency) for the CAN-Module? All examples use 8MHz, but that won't work in my case.
Is there a chance to get 50k Baudrate with minmimal Tolerances with the 20MHz Crystal Oscillator or should I change it back to 12MHz?
