Other Parts Discussed in Thread: TIDM-SERVER-PWR-MON, MSP430I2040
My customer made a smart plug by referring to the TIDM-SERVER-PWR-MON.
It measures AC voltage, power and etc.
When the board is connected to an one outlet of individual switch multi-tap as shown below and the switch of another outlet is repeatedly turned on/off, sometimes the MCU doesn't work and seems to be frozen.
At this time, MSP430 was not reset even though a signal changing from Low to High was input to the RST/NMI pin.
In order to restart the MCU, the power must be turned off and then turned on again.
This symptom is reproduced the same in the TIDM-SERVER-PWR-MON.
I'd like to know why the RST pin does not work and how to recover except power off when MCU gets hang.
