CADRCC – CC-ADC Regular Charge 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:

1. Values in the table are shown with the CADVSE set to both 0 and 1.

The CC-ADC Regular Charge Current Register does not affect the setting of the CC-ADC Con-

version Complete Interrupt Flag.

19.7.7

CADRDC – CC-ADC Regular Discharge Current

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

in the Table 19-5.
