Appendix B: Disable AX88796B voltage regulator
AX88796B integrates an on-chip 3.3V to 1.8V voltage regulator for single-power supply system design. If the
system have 1.8V power source already, user may like to disable AX88796B voltage regulator and use the existing
1.8V power source (probably a higher efficiency version). In that case, user can connect VCC3R3 (pin-10) and
GND3R3 (pin-11) to ground, keep V18F (pin-9) open, and set REGSTB bit of PMR register (see Page3 Offset 0BH
bit-4 in section 5.1.56 Power Management Register (PMR)) to 0 (i.e. logic "low") to avoid the leakage current.
Please refer to below picture for details.
Note: If user connects the VCC3R3 to 3.3V VCC and wants to disable the internal voltage regulator of AX88796B,
the REGSTB bit of PMR register should be set to 1 to set the regulator in standby mode to reduce the leakage
current.
