1 AC inputs during testing are driven at DVDD 0.5 V for a Logic 1 and 0.45 V for a Logic 0. Timing measurements are made at VIH minimum for a Logic 1 and VIL maximum for
a Logic 0, as shown in Figure 4.
2 For 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 4.
3 CLOAD for all outputs = 80 pF, unless otherwise noted.
4 The ADuC832 internal PLL locks onto a multiple (512 times) the external crystal frequency of 32.768 kHz to provide a stable 16.78 MHz internal clock for the system.
The core can operate at this frequency or at a binary submultiple called Core_CLK, selected via the PLLCON SFR.
5 This number is measured at the default Core_CLK operating frequency of 2.09 MHz.
6 ADuC832 machine cycle time is nominally defined as 12/Core_CLK.
