Abstract

A keyboard control device and method are applied to a notebook computer and mainly provide signal transmission between a host system and a keyboard scan matrix via the keyboard control device. The keyboard control device includes a keyboard control unit, a PS/2 interface control unit and a keyboard encoding unit, in which a transmission interface between the PS/2 interface control unit and the keyboard encoding unit contains a data request line, a data transmission line, a command request line and a command transmission line. Before transmitting data or command between the PS/2 interface control unit and the keyboard encoding unit, a notification signal is sent first, and then a transmission signal of data or command is sent out. The present invention can simplify the transmission design between the PS/2 interface control unit and the keyboard encoding unit.
