5.13.2 Power-Down Sequencing
For proper power down of the CC3220MODx 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.
5.13.3 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.
5.13.4 Wake Up From Hibernate Timing
NOTE
The internal 32.768-kHz XTAL is kept enabled by default when the module goes to
hibernate.
