Low Frequency is killing chip #200

Hello Bogdan, im trying to use the HX711 with lower Arduino Nano Frequency. I am using MiniCore and an external ISP Programmer. when setting CPU to 8Mhz internal it seems to be fine but on even lower Frequencies it just kills the chip. Sometimes the HX711 even draws so much current, that it becomes extremly hot and the voltage drops to 1.3 V instead of 5 V after the LDO (the LDO is hot then too). when measuring with an Ohm-Meter its not possible to find any differences.

is this issue known? why is it happening? how can it be fixed ?

thanks for the lib !

Christian
