5.14.2 Power-Down Sequencing

For proper power down of the CC3220MODx and CC3220MODAx module, ensure that the nRESET (pin

35) and nHIB (pin 4) pins have remained in a known state for a minimum of 200 ms before removing

power from the module.

5.14.3 Device Reset

When a device restart is required, the user may issue a negative pulse to the nRESET pin. The user must

ensure the reset is properly applied: A negative reset pulse (on pin 35) of at least 200-mS duration.
