Higher = less sensitive
Higher = more hysteresis
Higher = slower, more robust
Tndc = (NDC+1) x Tbs
Tpdc = (PDC+1) x Tbs
BG1: The reference is volatile
BG2: Reference is stored in EEPROM
Negative: detects a drop of Cx
Positive: detects a rise of Cx
Can only be disabled when SC = 0
Reference (BG modes), Threshold (OBJ mode)
SC = 0
SC > 0
Calculation / Notes
Tmod = (MOD + 1) x 256 x Tbs
Tmod = (MOD + 1) x 16 x Tbs
