STC8G1K08 When power is applied to the ports, a high level

Kol9***

Hey
After power on, the ports are high.
How to have a low level when the power is turned on on the ports?

Set the port register （e.g. P0）to 0 at first, and then initialize the port mode registers （e.g. P0M0 and P0M1） when power on initial

like this:
P0 = 0x00;
P0M0 = 0x00;
P0M1 = 0x00;
