Accum: Accumulator Master Enable bit
“Accum” is a master enable for Accl, AccT and AccV. If any combination of “Accl”, “AccT” and
“AccV” are enabled, Accum must also be enabled to permit accumulation. If “Accum” is ‘ 0 ’, no
accumulation will occur regardless of the settings in “Accl”, “AccT” and “AccV”.
1 = Accumulation enabled
0 = Accumulation disabled
Accl: Current Accumulation Enable bit
When “AccI” is set to a ‘ 1 ’, current accumulation is enabled. The DCA and CCA registers will
periodically add the value of the Ires register. Also, the DCT and CCT elapsed time counter
registers will count during discharge and charge, respectively. When “AccI” is cleared to ‘ 0 ’,
current accumulation is disabled.
1 = Current accumulation enabled
0 = Current accumulation disabled
AccT: Accumulate Temperature Enable bit
When “Acct” is set to a ‘ 1 ’, accumulation will be enabled in TA. TA will accumulate results from
the AD5 Result register and the TAT elapsed time counter will increment. When “Acct” is
cleared to ‘ 0 ’, TA accumulation will be disabled.
1 = Accumulate temperature enabled
0 = Accumulate temperature disabled
AccV: Accumulate Voltage from VC2 Enable bit
When “AccV” is ‘ 0 ’, accumulation in TA will be updated by the VC1res register. When “AccV” is
‘ 1 ’, accumulation in TA will be updated by the VC2res register.
tsel: Temperature Selection bit
When “tsel” is ‘ 0 ’, the internal temperature sensor is used for accumulation. When “tsel” is ‘ 1 ’,
the external temperature sensor is used for accumulation.
1 = External temperature sensor selected
0 = Internal temperature sensor selected
Reserved: Reserved bit location

‘1’ = Bit is set
