You can monitor an expression that uses the following types of operands only:
If you monitor an enumerated variable, a comment appears to the right of the value. If the value of the variable matches one of the enumerated types, the comment contains the name of the first enumerated type that matches the value of the variable. If the length of the enumerated name does not fit in the monitor, the contents appear as an empty entry field.
The comment (empty or not) lets you distinguish between a valid enumerated value and an invalid value. An invalid value does not have a comment to its right.
You cannot update an enumerated variable by entering an enumerated type. You must enter a value or expression. If the value is a valid enumerated value, the comment to the right of it is updated.
Bit fields are supported for C/C++ compiled code only. You can
display and update bit fields, but you cannot use them in
expressions. You cannot look at variables that have been defined
using the #define preprocessor directive.
