I found two problem on Processor Expert. Are these reported ?
CW10.5, CPU KL16
Default value of Modulo counter is 0. I think this should be 0xFFFF.
Clock setting has a bug. The baud rate that is shown "Baud rate" is missing. It looks like the baud rate is calculated with ++divisor.
For example, Baud rate divisor 6 should be Baud rate 249600 baud but 213942.857 baud under bus clock is 23.9616MHz.
