BOOL initial_SIO(BYTE Isolate_Type, BYTE DIO_NPN)
Initial machine for IO and watch dogtimer.
Isolate_Type : DIO type.
1 : Isolated DIO;
0 : Non-Isolated DIO(GPIO).
DIO_NPN : DI/DO type.
1 : PNP (Source) mode for European rule;
0 : NPN (Sink) mode for Japanese rule.
Return :
TRUE (1) : Success.
FALSE (0) : Fail (Driver not exists, or version is too old, or machine not match).
BOOL get_IO1_configuration(BYTE *Iso, BYTE *DI_mode, BYTE *DO_
mode, WORD *Mask)

1 : PNP (Source) mode for European rule;
0 : NPN (Sink) mode for Japanese rule.
Mask ([15:0]) : In/Out, pin setting by hexadecimal bitmask only for Non-
Isolated DIO(GPIO).
1 : Output;
0 : Input
Return :
