42.8.12 ADC Interrupt Status Register
Name: ADC_ISR
Address: 0xF804C030
Access: Read-only
• EOCx: End of Conversion x
0: The corresponding analog channel is disabled, or the conversion is not finished. This flag is cleared when reading the corre-
sponding ADC_CDRx registers.
1: The corresponding analog channel is enabled and conversion is complete.
•XRDY: Touchscreen XPOS Measure Ready
0: No Measure has been performed since the last read of ADC_XPOSR.
1: At least one Measure has been performed since the last read of ADC_ISR.
•YRDY: Touchscreen YPOS Measure Ready
0: No Measure has been performed since the last read of ADC_YPOSR.
1: At least one Measure has been performed since the last read of ADC_ISR.
•PRDY: Touchscreen Pressure Measure Ready
0: No Measure has been performed since the last read of ADC_PRESSR.
1: At least one Measure has been performed since the last read of ADC_ISR.
• DRDY: Data Ready
0: No data has been converted since the last read of ADC_LCDR.
1: At least one data has been converted and is available in ADC_LCDR.
• GOVRE: General Overrun Error
0: No General Overrun Error occurred since the last read of ADC_ISR.
1: At least one General Overrun Error has occurred since the last read of ADC_ISR.
• COMPE: Comparison Error
0: No Comparison Error since the last read of ADC_ISR.
1: At least one Comparison Error (defined in the ADC_EMR and ADC_CWR registers) has occurred since the last read of
ADC_ISR.
• PEN: Pen contact
0: No pen contact since the last read of ADC_ISR.
1: At least one pen contact since the last read of ADC_ISR.
