ABSTRACT:
A key signals input apparatus and related operating method used for reducing chip I/O number is described. The key signals input apparatus has a plurality of keys and a signal conversion module. The signal conversion module converts key signals into an analog voltage before directing to the chip for further processing. An analog signal decoding module designed in the chip decodes the analog signal so as to recover a plurality of input key values such that the chip may perform further operations according to the indication of the key signals.
