9.3. Oscillator-Fail Reset
If the system clock derived from the oscillator fails for any reason after oscillator initialization is complete, the reset
circuitry will drive the /RST pin low and return the CP2200/1 to the reset state. The CP2200/1 will remain in the
reset state for approximately 1 ms then exit the reset state in the same manner as that for the power-on reset.
9.4. External Pin Reset
The external /RST pin provides a means for external circuitry to force the CP2200/1 into a reset state. Asserting the
/RST pin low will cause the CP2200/1 to enter the reset state. It is recommended to provide an external pull-up
and/or decoupling capacitor of the /RST pin to avoid erroneous noise-induced resets. The CP2200/1 will exit the
reset state approximately 4 µs after a logic high is detected on /RST.
