1. RSTIN assertion can be released there. Refer also to Section 21.1 for details on minimum pulse duration.
2. If during the reset condition (RSTIN low), RPD voltage drops below the threshold voltage (about 2.5V for 5V operation),
3. RSTIN pin is pulled low if bit BDRSTEN (bit 3 of SYSCON register) was previously set by software.
4. Minimum RSTIN low pulse duration shall also be longer than 500ns to guarantee the pulse is not masked by the
