offset zero
Name (I2C, ResourceTemplate(){
I2CSerialBus(0x5a,,100000,, "\_SB.I2C",,,,RawDataBuffer(){1,6})
})

{
Connection(I2C)
// Specify connection resource information
AccessAs(BufferAcc, AttribWord)
// Use the GenericSerialBus
// Read/Write Word protocol
FLD0, 8, // Virtual register at command value 0.
FLD1, 8, // Virtual register at command value 1.
Field(TOP1, BufferAcc, NoLock, Preserve)
{
Connection(I2CSerialBus(0x5b,,100000,, "\_SB.I2C",,,,RawDataBuffer(){3,9}))
AccessAs(BufferAcc, AttribBytes (16))
FLD2, 8 // Virtual register at command value 0.
}
// Create the GenericSerialBus data buffer
Name(BUFF, Buffer(34){})
CreateByteField(BUFF, 0x00, STAT)
CreateWordField(BUFF, 0x02, DATA)
// Create GenericSerialBus data buffer as BUFF
// STAT = Status (Byte)
// DATA = Data (Word)
Description
The Connection macro declares the connection attributes for subsequent fields defined within the
Field declaration.
