2007 IFI default code question

[Japper]

In the IFI 2007 default code main.c , there is a condition statement (see below) where if _SIMULATOR is defined then
statusflag.NEW_SPI_DATA is set to 1 and the slow loop (which execute every 26.2ms) is used., otherwise
it is never entered.

It is my assumption that because _SIMULATOR is defined in the default.h header file that this slow loop
will always be executed.

Why would you not want to use the slow loop (and remove the definition in the header file)?

Here is the code:
============
void main (void)
{
#ifdef UNCHANGEABLE_DEFINITION_AREA
IFI_Initialization (); /* DO NOT CHANGE! */
#endif

User_Initialization(); /* You edit this in user_routines.c */

statusflag.NEW_SPI_DATA = 0; /* DO NOT CHANGE! */

while (1) /* This loop will repeat indefinitely. */
{
#ifdef _SIMULATOR
statusflag.NEW_SPI_DATA = 1;
#endif

if (statusflag.NEW_SPI_DATA) /* 26.2ms loop area */
{ /* I'm slow! I only execute every 26.2ms because */
/* that's how fast the Master uP gives me data. */
Process_Data_From_Master_uP(); /* You edit this in user_routines.c */

if (autonomous_mode) /* DO NOT CHANGE! */
{
User_Autonomous_Code(); /* You edit this in user_routines_fast.c */
}
}
Process_Data_From_Local_IO(); /* You edit this in user_routines_fast.c */
/* I'm fast! I execute during every loop.*/
} /* while (1) */
} /* END of Main */
