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.
