Abstract
A button control method for a built-in audio codec of a portable electronic apparatus, and the button control method includes the following steps. A plurality of button signals generated by a button unit is first detected during a button detection period. Next, the button signals are sequentially recorded during the button detection period. The processing unit matches and identifies the button signals provided thereto to generate a control command accordingly to correspondingly control the portable electronic apparatus.
Claims14
A portable electronic apparatus, comprising:
- an audio codec comprising:
- a button detector, operative to sequentially detect a plurality of button signals generated by a button unit during a button detection period;
- a register coupled to the button detector, operative to sequentially record the button signals during the button detection period;
- and
- a processing unit coupled to the audio codec, configured to operatively identify the button signals recorded in the register and generate a control command accordingly to correspondingly control the portable electronic apparatus.
A button control method for an audio codec of a portable electronic apparatus, the button control method comprising:
- detecting a plurality of button signals generated by a button unit during a button detection period;
- recording the button signals detected during the detection period, sequentially;
- and
- providing the button signals sequentially recorded during the button detection period to a processing unit for the processing unit to match and identify the button signals recorded and to generate a control command controlling the operation of the portable electronic apparatus.
