I
Power-Save (active high). This feature isolates the M670’s data bus
interface from the host preventing other bus activities that cause
higher power drain during sleep mode. See Sleep Mode with Auto
Wake-up and Power-Save Feature section for details. This pin does
not have a pull-down resistor. This input should be connected to
GND when not used.
RESET

I
This input is active high. A 40 ns minimum active pulse on this pin
will reset the internal registers and all outputs of the UART. The
UART transmitter output will be held at logic 1, the receiver input
will be ignored and outputs are reset during reset period (see UART
Reset Conditions).

Pwr
The center pad on the backside of the QFN package is metallic and
should be connected to GND on the PCB. The thermal pad size on
the PCB should be the approximate size of this center pad and
should be solder mask defined. The solder mask opening should be
at least 0.0025" inwards from the edge of the PCB thermal pad.
