I should check the bit value of the TDCEN but I have a problem.


My problem is as below.

How can I change the bit of TDCEN and confirm whether it is changed or not?

 - I changed the bit of TDCEN at the EmbSys Registers but these bits were not changed.

 - So I changed these bits at the source code, but I was not sure that these bits were changed.

   Because these bits at the EmbSys Registers were changed(1) during RUN but were returned to initial value(0) during SUSPEND.

 - In other words, I could not confirm that  the bit value of TDCEN was changed.



■ At the EmbSys Registers :

 1. I changed TDCEN bit to 1

 2. but this bit was not changed (the bit was returned to initial value 0, TDC is disabled)


■ At the source code : 

 1. I changed TDCEN bit to 1

< Before code change >

< After code change : from x to 1 >

 2. and TDCEN bit was changed (enabled) during RUN.

 3. but TDCEN bit was returned to initial value (disabled) during SUSPEND

Thank you
