PWM: Internal Pullups Briefly Enabled During Power Up

Revision(s) Affected

0

Details

During power up, the pullups on the PWM pins are forced on briefly. This causes a low current glitch on the pin. This is not an issue during a warm reset.

Workaround(s)

This can be overcome by using a 1–2 kΩ resistor to ground the pin.
