A1.4.6.3 reset Process
the basic reset process sequence is as follows.
1. Snapshot
2. Clearing the integrated values
3. Reset count increment
4. Judging out_tRIP and out_PtRIP (see a2.5)
1) Snapshot
Saves the following values in the specified param-
eters before clearing the integrated values. these
values will be retained until the next reset is made.
StotaL = total
SRtotaL = Rtotal
SSP = totaL_SP
2) Clearing the integrated values
the reset process clears the total. atotal and Rtotal
values in the internal registers.
total = 0
atotal = 0
Rtotal = 0
3) reset count increment
Each time a reset is made, the n_RESEt parameter
will be incremented.
the high limit is 999,999 and if this limit is exceeded,
the count returns to "0".
4) Judging OUT_TrIP and OUT_PTrIP (see A2.5)
out_tRIP and out_PtRIP are judged again on the
basis of the cleared integrated values.
there atre three options relating to a reset:
i Confirm reset (bit 8 of IntEG_oPtS)
ii Carry (bit 6 of IntEG_oPtS)
iii Generate reset event (bit 9 of IntEG_oPtS)
i Confirm reset (bit 8 of IntEG_oPtS)
If this option is enabled, the next reset is rejected
until "1" is set to RESEt_ConFIRM.
ii Carry (bit 6 of IntEG_oPtS)
If this option is enabled while IntEG_tYPE is
uP_auto or Dn_auto, the value exceeding the
threshold at a reset will bw carried into the next
integration.
If IntEG_tYPE is any setting other than uP_auto
or Dn_auto, this option is irrelevant.
iii Generate reset event (bit 9 of IntEG_oPtS)
If this option is enabled, an alert event is generated
if a reset occurs.
