DIGITAL PIN13 (IO13*) on Micro defaults to PWM? Need straight digital

I tried to control IO13 (pin32 on Atmega32u4) with pinmode OUTPUT, but what I get appears to be a PWM function, not a direct, turn on, turn off.

How do I disconnect the PWM override, and make it so I can control it as a simple digital PIN?

What I get when I turn “ON” this pin is an oscillation (on-off-on-off) about 427Hz with varying pulse width.

The code fragment in the setup routine below worked for other I/O pins I’m testing to get ready for implementing LCD interface control:

digitalWrite(LED_BUILTIN,LOW);
digitalWrite(LED_BUILTIN,HIGH);
delay(2);
digitalWrite(LED_BUILTIN,LOW);
delay(2000);
