(30ms) delay section
④
-Configuration value read point
⑤
-Rising section to reset release level
-32ms after BODR or external
reset is released
⑥
-Reset release point (BIT overflow)
-BIT is used to ensure oscillation
stability time
⑦
-Normal operation

13.6 External RESETB Input
External reset pin is a Schmitt Trigger type input. External reset input should be asserted low at least
for typical 8us(the clock source of Internal RING oscillator) for normal reset function.
