Hi,
What I've implenmented:
1. using PIO6 as input to capture rising and falling edge of input signal
2. deepsleep is enabled
Problem:
1. Pull SPI_PIO# to ground, works all good
2. after step #1, pull SPI_PIO# to 3V3. from this moment, power consumption rising higher
What I tried:
1. disable PIO6 settings
2. after toggling SPI_PIO#, power consumption is as low as expected
Would someone share some thoughts on this?
B.R.
Asserting the SPIO_PIO enables the debug section of the silicon which contibues to consume power.
In an actual end product the SPIO_PIO is not expected to be asserted for any reason.
