After nrf52840 uses the SPIM3 peripheral to send data, turn off the SPIM3 peripheral to enter low power consumption, and there will be 700UA current; if the SPIM3 peripheral is not used to send data (only for SPIM3 initialization, after entering low power consumption, only 15UA current). Excuse me, how can I use the SPIM3 peripheral to send data, and after it can enter low power consumption, there is only 15UA current.
