29.5.2 A/D Global Data Register (AD0GDR - 0x4003 4004)
29.5.3 A/D Interrupt Enable register (AD0INTEN - 0x4003 400C)
The A/D Global Data Register holds the result of the most recent A/D conversion that has
completed, and also includes copies of the status flags that go with that conversion.
Results of ADC conversion can be read in one of two ways. One is to use the A/D Global
Data Register to read all data from the ADC. Another is to use the
Registers
OVERRUN flags can otherwise get out of synch between the AD0GDR and the
Channel Data Register
This register allows control over which A/D channels generate an interrupt when a
conversion is complete. For example, it may be desirable to use some A/D channels to
monitor sensors by continuously performing conversions on them. The most recent
results are read by the application program whenever they are needed. In this case, an
interrupt is not desirable at the end of each conversion for some A/D channels.

Description
Reserved, user software should not write ones to reserved bits. The value read from
a reserved bit is not defined.
When DONE is 1, this field contains a binary fraction representing the voltage on
the AD0[n] pin selected by the SEL field, as it falls within the range of V

Reserved, user software should not write ones to reserved bits. The value read from
a reserved bit is not defined.
These bits contain the channel from which the RESULT bits were converted (e.g.
000 identifies channel 0, 001 channel 1...).
Reserved, user software should not write ones to reserved bits. The value read from
a reserved bit is not defined.
This bit is 1 in burst mode if the results of one or more conversions was (were) lost
and overwritten before the conversion that produced the result in the RESULT bits.
This bit is cleared by reading this register.
This bit is set to 1 when an A/D conversion completes. It is cleared when this
register is read and when the ADCR is written. If the ADCR is written while a
conversion is still in progress, this bit is set and a new conversion is started.

Description
Completion of a conversion on ADC channel 0 will not generate an interrupt.
Completion of a conversion on ADC channel 0 will generate an interrupt.
Completion of a conversion on ADC channel 1 will not generate an interrupt.
Completion of a conversion on ADC channel 1 will generate an interrupt.
Completion of a conversion on ADC channel 2 will not generate an interrupt.
Completion of a conversion on ADC channel 2 will generate an interrupt.
