5.3 A/D Status Register (AD0STAT - 0xE003 4030)
Table 594: A/D Global Data Register (AD0GDR - address 0xE003 4004) bit description
The A/D Status register allows checking the status of all A/D channels simultaneously.
The DONE and OVERRUN flags appearing in the ADDRn register for each A/D channel
are mirrored in ADSTAT. The interrupt flag (the logical OR of all DONE flags) is also found
in ADSTAT.

Description
These bits always read as zeroes. They provide compatible expansion
room for future, higher-resolution A/D converters.
When DONE is 1, this field contains a binary fraction representing the
voltage on the Ain pin selected by the SEL field, divided by the voltage
on the V
pin was less than, equal to, or close to that on V
indicates that the voltage on Ain was close to, equal to, or greater than
that on V
These bits always read as zeroes. They allow accumulation of
successive A/D values without AND-masking, for at least 256 values
without overflow into the CHN field.
These bits contain the channel from which the LS bits were converted.
These bits always read as zeroes. They could be used for expansion of
the CHN field in future compatible A/D converters that can convert more
channels.
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 LS bits. In non-FIFO operation, 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.
A/D channel Done flags is asserted and enabled to contribute to the
A/D interrupt via the ADINTEN register.
