Narrow down by specifying conditions

Is it okay to generate the 1.8V power supply for VCCINT of MAX V from the power supply used for VCCIO with a resistive voltage divider circuit?
No, do not supply VCCINT with power generated by a resistive voltage divider.
When supplying a power supply created by a resistive voltage dividing circuit, it becomes impossible to supply a stable power supply voltage, so MAX V operation cannot be guaranteed.
A possible reason for this is that when the load on MAX V, which is the connection destination, increases, the power supply voltage changes and the VCCINT specified value of MAX V is exceeded.
Be sure to generate a power supply voltage from a regulator, etc., and supply it to VCCINT.
