REF may be left floating if the internally generated 2.5 V supply is enabled. Use of an external reference is recommended. 184 analog REF REF 185 analog XN XN 186 analog XP XP 187 analog YN YN 188 analog YP YP 189 analog WIPER WIPER 190 analog INAUX0 INAUX0 191 analog INAUX1 INAUX1 192 analog INAUX2 INAUX2 193 power NVCC_DRYICE NVCC_DRYICE 194 3V3 A [9] A [9] 195 3V3 A [11] A [11] 196 3V3 A [12] A [12] 197 NC not connected 198 NC not connected 199 NC not connected 200 GND GND Touscreen ADC input channels General purpose measurements channels DRYICE power supply output.
