8.3.4 Manual Reset (MR) Input for X2SON (DPW) Package Only

The manual reset (MR) input allows a processor GPIO or other logic circuits to initiate a reset. A logic low on MR with pulse duration longer than tMR_RES will cause reset output to assert. After MR returns to a logic high
(VMR_H) and VDD is above VIT+, reset is deasserted after the user programmed reset time delay (tD) expires.

If MR is not controlled externally, then MR can be left disconnected. MR is internally connected to VDD through a pull-up resistor RMR shown in Section 8.2. If the logic signal controlling MR is less than VDD, then additional current flows from VDD into MR internally. For minimum current consumption, drive MR to either VDD or GND.
VMR should not be higher than VDD voltage.
