Placing no jumpers on the block ensures that the line is pulled low using 100K pull down resistors.
Placing the jumper pulls the pin high using a 10K resistor.

Note
Table 2-7. Push-Button Definitions
This is used to reset the CC3235MOD device. This signal is also output on the 20-pin connector
to reset any external BoosterPack which may be stacked. The reset can be isolated using the RST
jumper at the isolation block.
When pushed, GPIO_13 is pulled to VCC.
When pushed, GPIO_22 is pulled to VCC.
Pressing this button and toggling RESET restores the factory default image on the serial flash.
This can be used to recover a corrupted serial flash, provided the s-flash was programmed with a
recovery image.
Table 2-8. LED Indicators
Use
Debug Indicates the state of the JTAG emulator. For TI use only.
Indicates the state of the NRESET pin. If this LED is on, the device is
nRESET
functional.
Power Indicates when the 3.3-V power is supplied to the board.
GPIO_09 Glows when the GPIO is logic-1.
(1)
GPIO_10 Glows when the GPIO is logic-1.
(1)
GPIO_11 Glows when the GPIO is logic-1.
Factory Reset Indicates that the push-button for the factory reset is pressed.

C. Whenever the pullups are enabled, the LEDs glow by default without configuring the
sheet.
