Hi,
I am referencing page 8 of datasheet for tca8418. On power up, but (?) before boot up, before processor writes to tca8418 what is the status of the row and column pins. I assume internal pull up is active.
I ask because I am looking for an alternative boot (uboot would poll a gpio) and in finished unit, only
the keyboard contacts allow this if I hold down a key while powering/boot of the unit.
Thanks in advanced for your reply.
