To execute a source compile on the M3T-NC30WA, I treat the enumerator by the generated code modifying option "-fCE" as an

unsigned char type, rather than int type. However, when I reference the enumerator type variable with the M3T-PD30 (display by

moving the mouse curser to the variable), it displays the form in 16 bits instead. Why?

The enumerator type variables are treated as 2-byte variables by the M3T-PD30. Even if you specify the enumerator as a 1-byte

variable in the compiler, the enumerator type variable will be displayed in 2 bytes. However, you can reference the variable

correctly by casting and registering it in the C-watch window, as done in the program below.

[Example Program]

----------------------------------

typedef enum eTag {

ENUM0=0,

ENUM1,

ENUM2,

...

} ENUMTYPE;

ENUMTYPE enEnum;

----------------------------------

[Example of Registration in C Watch Window]

----------------------------------

(eTag)(unsigned char)enEnum

----------------------------------

When registering in the C watch window, make sure you cast with [enumerator tag (shown as "eTag" above)]. Do not cast with the

type you declared in typedef.
