Note 1. All voltages with respect to ground.
Note 2. VSS1 and VSS2 must be connected to the same analog ground plane.
Note 3. XP, YP, XN, YN pins. Max is smaller value between (AVDD+0.3)V or 6.0V.
Note 4. DIN, CSN, SCLK, RESETN, R1 ~ R5, GP0 ~ GP7 pins. Max is smaller value between (IOVDD+0.3)V or
6.0V. Pull-up resistors on BRCONT pin and GP0 ~ GP7 pins should be connected to (IOVDD+0.3) V or less
voltage.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
