Notes
1. VIL = VSS; VIH = VDD; all outputs and sense input lines unloaded. All open drain ports connected to VSS.
2. Crystal is connected between XTAL1 and XTAL2; T1 = VSS; INT/T0 = VDD.
17 AC CHARACTERISTICS
VDD = 5 V; Tamb = â20 to +70 °C; all voltages with respect to VSS; unless otherwise speciï¬ed.
