Field
Integrator Sum Exception flag
The SSE bit indicates an exceptional condition of the integrator accumulator. This flag generates
an Interrupt Request if enabled by the DECFILTER_MCR bit ERREN, and it is cleared by the
26
SSEC bit or by a soft reset. Integrator exceptions are defined in
SSE
exceptions.
0 No exception in the integrator accumulator.
1 Integrator accumulator exception.
Integrator Count Exception flag
The SSE bit indicates an exceptional condition of the integrator counter. This flag generates an
Interrupt Request if enabled by the DECFILTER_MCR bit ERREN, and it is cleared by the SCEC
27
bit or by a soft reset. Integrator exceptions are defined in
SCE
exceptions.
0 No exception in the integrator counter.
1 Integrator counter exception.
28 Reserved
Integrator Sum Overflow Flag
The SSOVF bit flag indicates an overflow of the integrator accumulator. This Flag is cleared by
the SSOVFC bit or by a soft reset.
0 No overflow in the integrator sample counter.
1 Integrator sample counter overflowed.
29
SSOVF
Note: The SCOVF bit samples the integrator accumulator overflow condition when and only when
Integrator Count Overflow Flag
The SCOVF bit flag indicates an overflow of the internal integrated sample counter. This Flag is
cleared by the SCOVFC bit or by a soft reset.
0 No overflow in the integrator sample counter.
1 Integrator sample counter overflowed.
30
SCOVF
Note: The SCOVF bit samples the integrator accumulator overflow condition when and only when
Integrator Data Overrun
The SVR bit indicates that an integration value and count in the registers DECFILTER_FINTVAL
and DECFILTER_FINTCNT was overwritten by a new integrator output request and was not read
31
by the CPU or DMA. This flag generates an Interrupt Request if enabled by the ERREN bit in the
SVR
Configuration Register. This Flag is cleared by the SVRC bit or by a soft reset.
0 Integrator Data Overrun did not occur.
1 Integrator Data Overrun occurred.

either registers DECFILTER_FINTVAL or DECFILTER_CINTCNT are updated. Therefore,
only one of the register pairs (DECFILTER_FINTVAL/DECFILTER_FINTCNT and
DECFILTER_CINTVAL/DECFILTER_CINTCNT) must be used by the application, in order
to avoid races.
