Trip point is ±1.5% from typical value.
Trip point is ±2.5% from typical value.
RST output is forced low. There is a current through the internal pull-up resistor.
This includes the current through the internal pull-up resistor and the reset power-up timer.
This specification allows this device to be used in PICmicro
Programming™ (ICSP™) (see device-specific programming specifications for voltage requirements). This specification
DOES NOT allow a continuos high voltage to be present on the open-drain output pin (V
V
limited to 2 mA and it is recommended that the device operational temperature be maintained between 0°C to 70°C
(+25°C preferred). For additional information, please refer to Figure 2-33.
This parameter is established by characterization and not 100% tested.
