CHAPTER 9. KEYMATRIX
The key matrix is connected the PXA255 GPIO. There are a total of 20 keys and except for the power supply key, 19 of those keys are connected to
the matrix. An illustration of connections is shown below. Additionally, because the center trigger, side trigger and [ • ] keys are connected as a sepa-
rate group to the other keys, This enables multiple simultaneous key inputs under specific conditions.
the matrix. An illustration of connections is shown below. Additionally, because the center trigger, side trigger and [ • ] keys are connected as a sepa-
rate group to the other keys, This enables multiple simultaneous key inputs under specific conditions.
The power supply key is connected to GPIO0 and GPIO22 of the CPU. GPIO0 is the OR of the power supply where the terminal charge stops detec-
tion and a determination of ON is based on the two conditions GPIO0 interruption and the GPIO22 level.
Existence of GPIO0 interruption, GPIO22=L
