FX2 Crash after writing in struct

I use a Cypress Fx2. It's no problem to write a value to dcf.sekunde but if i set dcf.minute to 0 or such a other value, the controller will stops/crash.

I'm not sure if the struct definition is correct or if i must reserver a address block for it. i hope someone can help me.

Thanks

Sorry for my bad English.

FX2_DCF-Clock.h

 typedef xdata struct signal {
unsigned char sekunde;
unsigned char minute;
unsigned char stunde;
unsigned char tag;
unsigned char wochentag;
unsigned char monat;
unsigned char jahr;
unsigned char synkro;
unsigned int  fehler_zaehler;
}tdcf;

extern tdcf dcf;

FX2_DCF-Clock.c

 txdata tdcf dcf;

 if(dcf.sekunde>59)
        {
                dcf.synkro=KEINSYNK;
                dcf.sekunde=0;

crash/stop

                dcf.minute=0;
                dcf.stunde=0;
        }

It is quite common with:

typedef struct tag_1 {
} tag_2;

tag_1 is the name it has within the "struct" namespace, i.e.:

struct node {
    struct node* next;
    int value;
};

struct node *head;  // ok
node *tail;         // invalid - "struct" keyword needed.

tag_2 is the type-defined name of the struct, i.e. intended for:

typedef struct {
    unsigned char age;
    char* name;
} person_t;

person_t charlie;
person_t benny;
