1AC inputs during testing are driven at DVDD – 0.5 V for a Logic 1, and 0.45 V for a Logic 0. T iming measurements are made at VIH min for a Logic 1, and VIL max  
for a Logic 0 as shown in Figure 2.  
2For timing purposes, a port pin is no longer floating when a 100 mV change from load voltage occurs. A port pin begins to float when a 100 mV change from the  
loaded VOH/VOL level occurs as shown in Figure 2.  
3CLOAD for Port0, ALE, PSEN outputs = 100 pF; CLOAD for all other outputs = 80 pF unless otherwise noted.  
4ADuC834 internal PLL locks onto a multiple (384 times) the external crystal frequency of 32.768 kHz to provide a Stable 12.583 MHz internal clock for the  
system. T he core can operate at this frequency or at a binary submultiple called Core_Clk, selected via the PLLCON SFR.  
5T his number is measured at the default Core_Clk operating frequency of 1.57 MHz.  
6ADuC834 Machine Cycle T ime is nominally defined as 12/Core_CLK.
