Question:
How do I use the UART Rx pin to wake up the PSoC® 6 device in Deep Sleep Mode?
Answer:
The SCB_UART_PDL component is not capable of waking up the device from the Deep Sleep mode. However, GPIO functionality can be used for this purpose. The GPIO interrupt can wake up the PSoC 6 device in Deep Sleep Mode when the device enters the Deep Sleep Mode. The UART Rx pin acts as the GPIO pin. Configure the UART Rx pin to wake up the PSoC 6 device in Deep Sleep Mode.
Figure 1 shows the Creator 4.2 project schematic and Figure 2 shows ModusToolbox configurator settings.
