COMMENT
When device reset is toggled, the MCU
bootloader kickstarts the procedure to
restore factory default images.
The recommended values of pull resistors are 100 kΩ for SOP0 and SOP1 and 2.7 kΩ for SOP2. The
application can use SOP2 for other functions after chip has powered up. However, to avoid spurious SOP
values from being sensed at power up, TI strongly recommends using the SOP2 pin only for output
signals. The SOP0 and SOP1 pins are multiplexed with the WLAN analog test pins and are not available
for other functions.
