I am trying out the LPC1768 UART0 to run at baud rates of 1Mbps and more. It seems that to make this work I need to set the PCLK to 100MHz. What is the significance of changing PCLK ? What are the software implications of changing the PCLK to 100MHz?
Also, I actually want to make this work at around 6Mbps. Would that be possible??
