// ACPI Embedded controller SMBus interface methods
//**********************************************************************;
// SMBR - SMBus read method
//
// Arg0 - Device address
// Arg1 - Command Code
// Arg2 - Data to write
// Arg3 - Protocol (basically RDWD, WRWD or RDBL)
Method(SMBR,4) {
If (LEqual(Arg3,RDBL)) {Store(0,DATB)}
Store(5, Local0)

Store(Arg0, ADDR) // Set the device address
Store(Arg1, SCMD) // Read Power unit value 0x3 offset

Store(Arg3, PRTC) // Set protocol - start SMBus transaction
Wait(SMBF, 0xFFF) // Wait till SMBus transaction completed
Reset(SMBF)
// One of known problems - ReadBlock of GLW SmartBattery may return BCNT=3
// and data as FF FF FF with no any SMBus errors. To avoid this:
// If(Or(SSTS,And(LEqual(Arg2,RDBL),And(LEqual(BCNT,3),LEqual(DAT0,0xFFFF)))))

Else {
