8.4 Device Functional Modes

8.4.1 RESET Output Low

When the VCC supply voltage is below the reset threshold (VIT-), the RESET pin will output logic low. RESET is

ensured to be a logic low for VCC > 0.95 V.

8.4.2 RESET Output High

When the VCC supply voltage exceeds the reset threshold (VIT-) plus the hysteresis voltage (VHYS), the RESET

remains asserted for a time period (tD) programmed by an external capacitor (CSRT); after this interval RESET

goes to logic high.
