CADRCC – CC-ADC Regular Charge Current
CADRDC – CC-ADC Regular Discharge Current
The CC-ADC Regular Charge Current Register determines the threshold level for the Regular
Charge Current detection. When the result of a CC-ADC Instantaneous Current conversion is
positive with a value greater than, or equal to, the Regular Charge Current level, the CC-ADC
Regular Current Interrupt Flag is set.
The value in this register defines the eight least significant bits of the Regular Charge Current
level in 2's complement format, where the most significant bits of the Regular Charge Current
level are always zero. The programmable range for the Regular Charge Current level is given in
the
Table 19-4.
Note:
The CC-ADC Regular Charge Current Register does not affect the setting of the CC-ADC Con-
version Complete Interrupt Flag.
The CC-ADC Regular Discharge Current Register determines the threshold level for the Regular
Discharge Current detection. When the result of a CC-ADC Instantaneous Current conversion is
negative with an absolute value greater than, or equal to, the Regular Discharge Current level,
the CC-ADC Regular Current Interrupt Flag is set.
The value in this register defines the eight least significant bits of the Regular Discharge Current
level in 2's complement format, where the most significant bits of the Regular Discharge Current
level are always one. The programmable range for the Regular Discharge Current level is given
