Which is the state of pins I/O during standby mode ?
I not found any document about.
RM0090 rev.13, 5.3.6 Standby mode
I/O states in Standby modeIn Standby mode, all I/O pins are high impedance except for:• Reset pad (still available)• RTC_AF1 pin (PC13) if configured for tamper, time stamp, RTC Alarm out, or RTCclock calibration out• WKUP pin (PA0), if enabled
Thank you !!!
all I/O pins are high impedance
How high is high ? Can you put a number to quantify the impedance ?
So waclawek.jan scores a straight 2 on the RTFM-O-Meter !
I was looking for "impedance", "Ohm", "Ω" and similar keywords, not "current".
So, we're talking about MΩ impedance, which isn't particularly high. I have voltage dividers in the same order, having one connected to such IOs will be impact the circuit.
IMO this is result of having the latchup protection circuitry.
Mind, this is generally a digital, not analog, IC.
