• Manufacturer Part Number: W83627F
• Description: LPC Interface I/o Plus Kbc, Game Port, Midi Port
• Manufacturer: Information Storage Devices, Inc

The second interface uses I
That is, the first address defined at CR[48h] can read/write all registers excluding Bank 1 and Bank 2
temperature sensor 2/3 registers. The second address defined at CR[4Ah] bit2-0 only read/write
temperature sensor 2 registers, and the third address defined at CR[4Ah] bit6-4 only can access
(read/write) temperature sensor 3 registers.
(b) Serial bus write to internal address register only
(a) Typical 2-byte read from preset pointer location (Temp, T
(a) Serial bus write to internal address register followed by the data byte
(c) Serial bus read from a register with the internal address register prefer to desired location
