Parameters are valid over operating temperature range unless otherwise specified.
Typical ratings are not guaranteed. The values listed are at room temperature (25 °C), nominal supply voltages.
Applies to standard I/O pins and RESET pin.
Characterized but not implemented as production test. Guaranteed by design.
