115 / 273 page ![]() 115 8042A–AVR–07/09 ATmega16HVB/32HVB 19.7.6 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.
