#define WDT_WINDOWED_TEST_TIMER_RESET_FLAG 0b10001010uThis is a macro is used to set a flag value to know which part if the test should be run. With the flag variable constaining this flag value, the WDT timer reset should be tested. The flag value chosen is arbritrary, but simply using 0x1 would make it harder to verify that the variable storing the flag is not corrupted.
