If you look at the beginning of User_Autonomous_Code() you see
Code:
while (autonomous_mode) /* DO NOT CHANGE! */
{
if (statusflag.NEW_SPI_DATA) /* 26.2ms loop area */
{
Getdata(&rxdata); /* DO NOT DELETE, or you will be stuck here forever! */
the non-autonomous mode code only excecutes on the first cycle of the autonomous mode, after that, it is in that loop there.
So that gets executed every 26.2ms, and Process_Data_From_Master_uP() is not.
I'm not sure what you are asking, do you want to know how long it takes for the code to run?
