// New File - Activate_Deactive_I.c

/* user will pass 1 or 0 to this function. */
/* If State =1, there is no change to GetDeltaMin ( ). It'll still pass two byte value from NVRAM to calling library. */
/* If State = 0, GetDeltaMin ( ) needs to pass 0 to calling library instead of two byte value from
from NVRAM. */
/* Please write this function and modify GetDeltaMin ( ). */
}

// New File - Activate_Deactivate.h

extern void Enable_Disable ( Boolean State); /* This header file must be included in file from where Enable_Disable ( ) will be called. */
/* I don't think Activate_Deactive_I.c needs to include this header file ? */
