Higher = less sensitive
Higher = more hysteresis
Higher = slower, more robust
BG1: The reference is volatile
BG2: Reference is stored in EEPROM
Negative: detects a drop of Cx
Positive: detects a rise of Cx
Burst rep interval = Tbs = SC x Ti
Can only be disabled when SC = 0

Calculation / Notes
Tndc = (NDC + 1) x 16 x Tbs
Tndc = (NDC + 1) x Tbs
Tpdc = (PDC + 1) x 16 x Tbs
Tpdc = (PDC + 1) x Tbs
Tmod = (MOD + 1) x 256 x Tbs
Tmod = (MOD + 1) x 16 x Tbs
