(1) TI recommends using the lowest possible drive strength that is adequate for the applications. This recommendation minimizes the risk of
interference to the WLAN radio and reduces any potential degradation of RF sensitivity and performance. The default drive strength
setting is 6 mA.
(2) The nRESET pin must be held below 0.6 V for the device to register a reset.
