☞
The average current consumption for full operation mode strongly depends on the RX/TX time
ratio and remains within the range between the peak values of RX and TX.

1PPS pad always use 1.8 V internally generated IO supply regardless of the VIO pad voltage.
6
RSTn pad internally pulled high to VIO voltage by 100k. During reset it should be below 0.2 V.
