5.3 External Reset (RESET)
The RESET input is the only external reset and is connected to an
internal Schmitt trigger. The external reset occurs whenever the RESET
input is driven below the lower threshold and remains in reset until the
RESET pin rises above the upper threshold. The upper and lower
thresholds are given in
Section 13. Electrical Specifications
.
5.4 Internal Resets
The three internally generated resets are:
Initial power-on reset (POR)
Computer operating properly (COP) watchdog timer
Low-voltage reset (LVR)
