Keyboards
The device keyboard is split between the main ITU 3x4 keyboard located on the engine board and the
remainder of the keyboard located on the S60 UI board on the other side of the slide module. All the keys
are located as part of the same matrix, and are connected directly to the APE ASIC in the case of the keys on
the engine PWB, and through ASIPs in the case of the keys on the S60 PWB.
