NOTE: CLK, CLK50, PCLK Remain in the High State until RES goes high and 8192 valid oscillator cycles have been registered by the 82C85

internal counter (TOST time period). After RES goes high and CLK, CLK50, PCLK become active, the RESET output will remain high

for minimum of 16 CLK cycles (TRST).
