Description

This function gets the touch-panel value requested by TP_RequestSamplingAsync, deeming it to have been set by the ARM7 and treating it as the calibrated screen coordinates. (X value ranges between 0 and 255; Y value ranges between 0 and 191) The value obtained here already accounts for chattering. If a response from ARM7 has not come yet, it may not be possible to obtain a correct value.
