Abstract
A processing system includes a sensor module and a determination module. The sensor module includes sensor circuitry coupled to transmitter electrodes and receiver electrodes. The sensor module is configured to transmit transmitter signals with the transmitter electrodes and receive resulting signals with the receiver electrodes. The determination module is configured to determine a presence of a passive pen in a sensing region using the resulting signals, determine a current ground mass state of the passive pen based on the resulting signals, and report, based on the current ground mass state, ground mass state information of the passive pen.
