Part Number: MSP430F5438A
Hi team,

As shown above, the customer configures the 5438A with a 20MHz active crystal.
The code of clock configuration is as follows:

With this configuration, both the main and sub-clock read back with the following two functions is 1048576 MHz. This is also true in practice with serial communication testing.
clockValue = UCS_getSMCLK();
clockValue = UCS_getMCLK();
Why is this? Customer want to configure both master and sub-clocks to 20 MHz.
Thanks.
Best Regards,
Cherry
