Hi all,
Doe's anyone know how to write a union type to external parallel EEPROM (AT28C64)?

The union type is:
typedef union {
uchar handle :1;
uchar input_status;
uchar intrnl_event;
uchar rcv_data[8];
uint measurement;
Time time;
Date date;
} rcvMSG;

I know how to write byte by byte but not this one. I also configured the external pointer to be rcvMSG instead of char but without luck.
