SPI don't work with Full Chip Simulation

Hi to all,
I'm trying to use a MC9S08GT60. I'm using Full Chip Simulation to verified that all the function works fine.
I've a data that I want send by SPI, but in Full Chip Simulation I can't write on the SPI1D register.
There is the code:

byte SPI_send(char data)
while (!SPI1S_SPTEF); /* Wait for Tx buffer empty */
SPI1S; /* Read of SPI1S with SPTEF=1 */
SPI1D = data; /* Send byte */
while (!SPI1S_SPRF); /* Wait for Rx buffer full */
return (SPI1D); /* Received byte value */

When I write data to SPI1D with "SPI1D = data" nothing happens!
The memory map don't change.

Where I fail?

Best regard,
