Hi
Iam using TWR-K70 board for interfacing LCD with SSD 1963 controller using Flex bus.
I am trying to measure Flex-bus clock (PTC3 - ALT 5 ) from the TWR module.But it is always showing 20 MHz
even when i change the flex bus frequency using SIM-CLKDIV1 Register.
I tried variying the clock from 40 MHz to 10 MHz but i am getting the same output (20 MHz).
Can any one help me with how to measure the Flex bus Clock

Hi ,
I have implemented a PE demo based on TWR-K70, I just enabled the port c clock gate and set PTC3 as clockout, and changed the flexbus clkout as below:
60MHz
40Mhz
seems no problem to output clock other than 20MHz, maybe it is a software issue, so I attached my project for your reference, please kindly refer to it for more details.
Hope that helps,
Have a great day,
Kan
