(1) All voltage values are with respect to VSSP.
(2) CDIV1 and CDIV2 should be of same type and tolerance. CDIV2 capacitance value should be at least three times the capacitance value of CDIV1 i.e. CDIV2 ≥ 3 × CDIV1.
(3) All capacitance values are absolute. Derating should be applied where necessary.
(4) Open-drain fail-safe output. When being used, an external pull-up resistor greater than 20kΩ to VDDP is recommended. When not being used, float pin or connect to VSSP.
