Rev. 1.0 | 7 3.3 SiWG917Y Reset The SiWG917Y can be reset by a few different sources: · A user pressing the RESET button. · The on-board debugger pulling the #POC_IN pin low. · An external debugger pulling the #POC_IN pin low. The figure below shows the reset options available on the kit. UG590: SiWx917Y Module Wi-Fi 6 and Bluetooth LE Explorer Kit User's Guide Hardware BUTTON RESET DBG RESET 0R (NM) SiWG917Y Module RESET_N POC_OUT POC_IN Figure 3.3. SiWx917Y Module Wi-Fi 6 and Bluetooth LE Explorer KitReset The Power On Control (POC) has two control options. POC_OUT Connected to POC_IN: The POC_IN input of the chip should be made high only after supplies are valid to ensure the IC is in safe state. The POC_IN can be connected externally to the internally generated POC_OUT signal or can be controlled from external source like R/C circuit. During power up, until the VBATT reaches 1.6 V , the POC_OUT signal stays low. Once the VBATT supply exceeds 1.6 V, the POC_OUT becomes high and the RESET_N is high at least 1.6 ms after VBATT supply is stable. External Control for POC_IN: The POC_IN and RESET_N signals can be controlled from an external source like R/C circuits. RESET_N will be pulled low if POC_IN is low. POC_IN should be made high only after supplies are valid to ensure the IC is in safe state. A pull-up R/C circuit is applied across it to provide a delay, so that POC_IN should be high after 0.6 ms and RESET_N should be high after 1 ms of POC_IN high. 3.4 Push Buttons and LEDs The kit has two user push buttons, marked BTN0 and BTN1, that are connected to GPIOs on the SiWG917Y Module. The BTN0 is connected to "deep sleep" wake-up pin UULP_VBAT_GPIO_2 and BTN1 is connected to GPIO_11, respectively, and they are debounced by an RC filter with a time constant of 1 ms. The logic state of a button is high while that button is not being pressed, and low when it is pressed. The kit also features two yellow LEDs, marked LED0 and LED1, that are controlled by GPIO pins on the SiWG917Y Module. The LEDs are connected to pin GPIO_10 and ULP_GPIO_2, respectively, in an active-high configuration.

More information is available in section 4. Debugging. silabs.com | Building a more connected world. Rev. 1.0 | 14 UG590: SiWx917Y Module Wi-Fi 6 and Bluetooth LE Explorer Kit User's Guide Debugging 4. Debugging The SiWx917Y Module Wi-Fi 6 and Bluetooth LE Explorer Kit contains an on-board SEGGER J-Link Debugger that interfaces to the target module using the Serial Wire Debug (SWD) interface. The debugger allows the user to download code and debug applications running in the target SiWG917. Additionally, it provides a virtual COM port (VCOM) to the host computer that is connected to the target device's serial port for general purpose communication between the running application and the host computer. The on-board debugger is accessible through the USB Type-C connector. 4.1 On-board Debugger The on-board debugger is a SEGGER J-Link debugger running on an EFM32 Giant Gecko. The debugger is directly connected to the debug and VCOM pins of the target SiWG917. When the debug USB cable is inserted, the on-board debugger is automatically activated and takes control of the debug and VCOM interfaces. This means that debug and communication will not work with an external debugger connected at the same time. The onboard LDO is also activated, providing power to the board. 4.2 Virtual COM Port The virtual COM port is a connection to a UART of the target SiWG917 and allows serial data to be sent and received from the device. The on-board debugger presents this as a virtual COM port on the host computer that shows up when the USB cable is inserted. Data is transferred between the host computer and the debugger through the USB connection, which emulates a serial port using the USB Communication Device Class (CDC). From the debugger, the data is passed on to the target device through a physical UART connection. The serial format is 115200 bps, 8 bits, no parity, and 1 stop bit by default. Note: Changing the baud rate for the COM port on the PC side does not influence the UART baud rate between the debugger and the target device. silabs.com | Building a more connected world.
