For LHT65 we recommend to use the white one show in possible issue 2. The pins being read must be set to OUTPUT mode by using CRL/CRH or pinMode() before using this. for STM32 ® - pinout Digital lines Analog Lines Interrupt Lines SPI Lines I2C Lines UART lines PWM lines System power supply VSYS RST Reset pin Reference Ground GND GND Reference Ground PA1 L PA2 R left ch. It will only read ‘0’ if the pin is connected to ground externally. These exceptions arise within Cortex core like reset, NMI, hard fault and error, debug, and SystTick timer interrupt.

And this problem could not be reproduced in our lab condition.
GPIO pin stands for the General-purpose input/output pin on MCU.To reset an ARM Cortex M by software, I can use the AIRCR register.I programmed an STM32F `Flash Release' to check a timing concern and have discovered that I have set STARTUP_FROM_RESET and cannot regain control of the CPU via JTAG, as warned in the STM32F10s_Startup. Ground of bluepill board – Pin 4 of ST-Link.
When using the output data registers, the compiler will have to generate a number of statements in order to set or reset a pin. Stm32 reset pin Set by hardware when a Low-power management reset occurs.
