This LSI has three on-chip keyboard buffer controller channels. The keyboard buffer controller is
provided with functions conforming to the PS/2 interface specifications.
Data transfer using the keyboard buffer controller employs a data line (KD) and a clock line
(KCLK), providing economical use of connectors, board surface area, etc. Figure 17.1 shows a
block diagram of the keyboard buffer controller.
