GPIO Sample Code
GPIO Setting
The GPIO function is provided by Nuvoton NCT6106D, and it can be accessed through its GPIO index/data port. To access the
GPIO register, write index to the index port, and then read/write from/to data port. The configuration on the CT-DR101 is
described as below.
Psuedo Code
#define AddrPort
0x2e
#define DataPort
0x2f
#define SIO_UnLock_Value
0x87
#define SIO_Lock_Value
0xaa
#define SIO_LDN_GPIO
0x07
#define GPIO_Port
0xF1
//Enter_Config
WriteByte (AddrPort, SIO_UnLock_Value);
WriteByte (AddrPort, SIO_UnLock_Value);
WriteByte (AddrPort, 0x07);
WriteByte (DataPort, SIO_LDN_GPIO);
//Set OUT1~OUT8Value
WriteByte (AddrPort, GPIO_Port);
WriteByte (DataPort, 0x00); //set OUT1~OUT4 value, OUT1=Bit0, OUT2=Bit1
// Read In1~In8 value
WriteByte (AddrPort, 0xED);
Data= ReadByte (DataPort); //Read In1~In4 value
// close config mode
WriteByte
(
