hmm i see you press ALL keys. Hard analyse why they key not work or what they do.
I sink
MC ot is Main control (button pressed)
PM - power message (ignor him i dont know why need switch porer mode many times)
FC - flash card control
in 162 and 165 use sw operator outher used by control or action.
i sink 0160 work too (they use sw too) but i dont know how.
You can post outher keys adress (if you know?). Some key do something but i dont know what key..
