Interrupt polarity for the PULSE edges. The default
polarity is falling edge.
INT_POL[3]=1: Interrupt on rising edge of YPULSE
INT_POL[2]=1: Interrupt on rising edge of XPULSE
INT_POL[1]=1: Interrupt on rising edge of VPULSE
INT_POL[0]=1: Interrupt on rising edge of WPULSE
—
Enable open-drain on the INTZ output. By default, the
pin is configured as a CMOS totem-pole output.
