Does the MAX3420E support active-low wired-OR interrupts? How about edge-active interrupts?

The MAX3420E supports both interrupt types, using a control bit called INTLEVEL. Setting INTLEVEL=1 makes the INT output pin open-drain, active-low for wired-OR applications. This mode requires an external pullup resistor to VL. Setting INTLEVEL=0 (the default value) makes the INT pin edge-active with a push-pull output driver. In edge mode, a second bit called POSINT sets the edge polarity to positive or negative.
