2.16 Reset signal (~RST)
This signal is used to force a reset procedure by providing low level during at
least 500µs. This signal has to be considered as an emergency reset only. A
reset procedure is already driven by an internal hardware during the power-up
sequence.
This signal can also be used to provide a reset to an external device. It then
behaves as an output. If no external reset is necessary this input can be left
open. If used (emergency reset), it has to be driven by an open collector or an
open drain.
