extern U08 FSCregister[FSC_REGISTER_LENGTH];
// but this register is not only accessible by
// FSCregister[i], but as well by special pointers like this:
extern U32 *status 							;
extern U32 *time_sec 							;
extern U16 *time_ms 							;
extern U16 *FR_period 							;

// using these pointers one can manipulate measurement values like this:
// res_value[3] = 453212;
// and then readout the most significant byte of this same value by accessing:
// FSCregister[92]; 
// I like this very much for asking the boards status ... this is just a copy of the registers,
// into the W5100 TX FIFO.
// submitting the measurement values is just a partial copy...
