Precautions for the internal device interface function

The following shows precautions for using an application that uses the internal device interface function.

(1) When the GDev_OpenMapping function is called

The GDev_OpenMapping function must be called after GT SoftGOT1000 is started.

(2) When the GDev_Read function or the GDev_Write function is called

The GDev_Read function and the GDev_Write function must be called while GT SoftGOT1000 is 
running.

(3) When exiting GT SoftGOT1000

If GT SoftGOT1000 has been exited in a status the GDev_OpenMapping function is called, the 
GDev_CloseUnMapping function must be called immediately.
If GT SoftGOT1000 is started again without the GDev_CloseUnMapping function called, after GT 
SoftGOT1000 is exited, GT SoftGOT1000 may not operate normally.
If GT SoftGOT1000 does not operate normally, the GDev_CloseUnMapping function should be 
called before GT SoftGOT1000 is exited.
