When debugging a portion of code related to the USART, I noticed that the US_CR location doesn't update. I've added the pointer to the USART0 as a watch variable. When stepping through the code, other registers in the structure such as US_BRGR update, but not the US_CR. Am I missing something?
I've verified this with the "AT91SAM7S-EK\Hello" project. I am using a Keil ULINK2 to debug.
