We switch several times the µC into Standby Mode and the current is as described in the specification.But sometimes over the Vdda Pin the current is 1mA. We switch adc/dac vrefint etc off. No BOR in use.We checked each Ports, but the current is comi...

Can't set Option Byte with the attached function for the Micro STM32L151CBT6A Only when the controller is new from factory. If we erase and reset the option bytes the STM32 afterwards new flashing it works.

Standby current is sometimes to high STM32L151CBT6A

Get Events from ST25R3916 stack in card emulation mode

Our problem is that the ST25R card emulation example works correctly for a while (with a smartphone on the antenna) and suddenly the ST25R3916 chip does not generate further interrupts.
