4.6 Pad State After Application of Power To Chip, But Before Reset Release
When a stable power is applied to the CC3220MODx module for the first time or when supply voltage is
restored to the proper value following a prior period with supply voltage below 1.5 V, the level of the digital
pads are undefined in the period starting from the release of nRESET and until the DIG_DCDC of the
CC3220x chip powers up. This period is less than approximately 10 ms. During this period, pads can be
internally pulled weakly in either direction. If a certain set of pins are required to have a definite value
during this pre-reset period, an appropriate pullup or pulldown must be used at the board level. The
recommended value of these external pullup or pulldown resistors is 2.7 kΩ.
