Hi,
There is a statement in MSP430 USB Hardware Design Guide P.18 that the PUR pin becomes an input and is judged after BOR reset.
1. Is there any information that the judgment will start within seconds after the BOR occurs?
2. How many seconds does the MCU need to be HIGH to recognize the PUR as HIGH?
Background of the question
The MCU may or may not recognize the PUR when the HIGH is long or short. We are investigating the timing when BUR judgment starts from the next waveform.
※This waveform pulls up R45 and intentionally outputs D +.
Thanks,
Koki
