INTRN or OP3-OP7 when used as interrupt outputs.
The test for open-drain outputs is intended to guarantee switching of the output transistor. Measurement of this response is referenced from the midpoint of the switching

test environment are pronounced and can greatly affect the resultant measurement.
C1 = C2
C1 and C2 should be chosen according to the crystal manufacturer’s specification.
C1 and C2 values will include any parasitic capacitance of the wiring and X1 X2 pins.
Gain at 3.6864MHz: 9 to 13 dB
Phase at 3.6864MHz: 272 to 276 degrees.
Package capacitance approximately 4pF.
