FINAL

Note 4: “NC” means: leave unconnected.

“GND” means internally connected to the module ground plane. Every GND pin should be connected to the main PCB.ground plane.

Note 5: All digital inputs have Schmitt trigger inputs. After reset all I/Os are set to input and all pull-up or pull-down resistors are enabled unless oth-

erwise specified.

PU = Pull-up resistor enabled, PD = Pull-down resistor enabled, I = input,

O = output, Hi-Z = high impedance, 1 = logic HIGH level, 0 = logic LOW level

Refer also to Px_DIR_REGs for INPUT/OUTPUT and Pull-up/Pull-down configurations

Note 6: All ULP pins use snap-back devices as ESD protection, which (when triggered) have a holding voltage below the typical battery voltage.

This means that the snap-back device of a ULP pin may remain conductive, when triggered while the pin is directly connected to the battery

voltage. If any of the ULP pins are directly or indirectly electrically accessible on the outside of the application, system level ESD precau-

tions must be taken to ensure that the snap-back device is not triggered while in active mode, to prevent the chip from being damaged.
