Regarding the polarity of the ACT_LED signal, is the following our understanding correct?
===
- If ACT_LED signal is Pulled Down, LED_ACT="ON" equals LED_ACT's voltage="HIGH level"
- If ACT_LED signal is Pulled Up, LED_ACT="ON" equals LED_ACT's voltage="LOW level"
*The polarity of the LEC_ACT signal is changed depends on pull up/down on the signal.
===
Our understanding is based on the following.
[Because these LED pins are also used as strap options, the polarity of the LED is dependent
on whether the pin is pulled up or down.]

Thank you.
