[bug #30604] Error in iox192d3.h #448

While using the ADC CH0 structure, I noticed an offset error in the ADC_t structure that defines where CH0 is positioned. The following is the example of what I see:/ Analog-to-Digital Converter / typedef struct ADC_struct { register8_t CTRLA;  / Control Register A / register8_t CTRLB;  / Control Register B / register8_t REFCTRL;  / Reference Control / register8_t EVCTRL;  / Event Control / register8_t PRESCALER;  / Clock Prescaler / register8_t CALCTRL;  / Calibration Control Register / register8_t INTFLAGS;  / Interrupt Flags / register8_t reserved_0x07; register8_t reserved_0x08; register8_t reserved_0x09; register8_t reserved_0x0A; register8_t reserved_0x0B; _WORDREGISTER(CAL);  / Calibration Value / register8_t reserved_0x0E; register8_t reserved_0x0F; _WORDREGISTER(CH0RES);  / Channel 0 Result / _WORDREGISTER(CMP);  / Compare Value / register8_t reserved_0x1A; register8_t reserved_0x1B; register8_t reserved_0x1C; register8_t reserved_0x1D; register8_t reserved_0x1E; register8_t reserved_0x1F; ADC_CH_t CH0;  / ADC Channel 0 / } ADC_t;

and this is the temporary fix I tried:

/ Analog-to-Digital Converter / typedef struct ADC_struct { register8_t CTRLA;  / Control Register A / register8_t CTRLB;  / Control Register B / register8_t REFCTRL;  / Reference Control / register8_t EVCTRL;  / Event Control / register8_t PRESCALER;  / Clock Prescaler / register8_t CALCTRL;  / Calibration Control Register / register8_t INTFLAGS;  / Interrupt Flags / register8_t reserved_0x07; register8_t reserved_0x08; register8_t reserved_0x09; register8_t reserved_0x0A; register8_t reserved_0x0B; _WORDREGISTER(CAL);  / Calibration Value / register8_t reserved_0x0E; register8_t reserved_0x0F; _WORDREGISTER(CH0RES);  / Channel 0 Result / register8_t reserved_0x01; register8_t reserved_0x02; register8_t reserved_0x03; register8_t reserved_0x04; register8_t reserved_0x05; register8_t reserved_0x06; _WORDREGISTER(CMP);  / Compare Value / register8_t reserved_0x1A; register8_t reserved_0x1B; register8_t reserved_0x1C; register8_t reserved_0x1D; register8_t reserved_0x1E; register8_t reserved_0x1F; ADC_CH_t CH0;  / ADC Channel 0 / } ADC_t;

It looks like this is due to the removal of other channels in other Xmega devices (CH1, CH2, CH3).

This could apply to other D3 device files.

Thanks Mike
