Notes
1. VIL = VSS; VIH = VDD; open drain outputs connected to VSS; all other outputs, including XTAL2, open (typical values
at 25 °C with crystal connected between XTAL1 and XTAL2).
2. VIL = VSS; VIH = VDD; RESET and T1 at VSS; INT/T0 at VDD; crystal connected between XTAL1 and XTAL2; open
drain outputs connected to VSS; all other outputs open.
