The internal timer counting is based on an 8Mhz clock input from X1, X2 ( or X2, with X1 connected to ground).

After the deassertion of RESET#, the VT82C42 will drive high at pin P23 and pin P27.

∗ Fully hardware implemented, 0.8µm CMOS Technology. ∗ Very high speed response of A20 GATE & reset. ∗ Support PS2 style mouse. ∗ Compatible with all major BIOS, including AWARD,.
