A1.4.3.2 Addition
the following three options are available for additions.
• totaL: adds two arguments values as is.
• FoRWaRD: adds two argument values,
regarding a negative value as "0".
• REVERSE: adds two argument values,
regarding a positive value as "0".
You can choose these options using bit 2 and bit
3 of IntEG_oPtS as follows:
the result of the adder is passed to the integrator.
If only one of the inputs is connected, the value of s
non-connected input will be ignored.
When bit 7 of IntEG_oPtS (add zero if bad) has
been set, if the status of a value after addition is
"BaD", the value after addition (increment) becomes
"0".
A1.4.4 Integrator
When addition is complete, its result will be
passed to the integrator.
Integration consists of combination of a reset
method and counting au/down. these are the fol-
lowing seven integration types, which can be set
using IntEG_tYPE.
1. uP_auto: Counts up with automatic reset
when totaLSP is reached.
2. uP_DEM: Counts up with demand reset.
3. Dn_auto: Counts down with automatic reset
when zero is reached.
4. Dn_DEM: Counts down with demand reset.
5. PERIoDIC: Counts up and is reset periodically
according to CLoCK_PER.
6. DEManD: Counts up and is reset on demand.
7. PER&DEM: Counts up and is reset periodically
or on demand.
Each type of integration is independently run as a
function.

these are the following 4 types of integration values:
1.
total: Integrates the result of the adder as is
2. atotal: Integrates the absolute value of the
result of the adder.
3. Rtotal: Integrates the absolute value of the
result of the adder only if the status of the
result is "BaD".
this value is used for the RtotaL value.
4. acctotal: am extension function. the result
of the adder is integrated as is and will not
be reset.
the value is used for the aCCuM_totaL (expand
parameter) value.
the table a2.1 shows the details of IntEG_tYPE.
