В Errata видел вот это: RES4 RES4 - Bug description: Module: General, Reset, No reset if external resistor exceeds certain value No reset of the device is performed if the external pull down resistor on RST/NMI pin is above a certain limit. The limits are: VCC=1.8V: maximum pull down resistor = 12kohm VCC=3.0V: maximum pull down resistor = 5kohm VCC=3.6V: maximum pull down resistor = 2.5kohm In addition, a higher current consumption occurs during high/low RST/NMI signal transition when using improper resistors. Workaround: Use external resistors below the mentioned values.
