Today I met a very interesting stuation with low power segment LCD.

After PMM_trigBOR() (soft reset) LCD draws extra current (~ 6uA) according to before soft reset.

If hard reset performed, there is no problem.

What this abnormality is ????

Hi, Mesut,

PMM_trigBOR() is software BOR. Some registers will not reset after the software BOR. It is different from the hardware reset of the reset pin. You can find the reset condition in the MSP430FR6047 user's guide -http://www.ti.com/lit/pdf/slau367

Thanks,

Lixin
