Receives the Pause Key command -A39F
Function : returns a code for data input through a Remote control
Format : #I
Explanation : The player returns a four-digit ASCII-Hex code that represents
commands sent through the remote control.
There are two code types, either a four-digit or eight-digit code (Extension
code). When the input command data is two words (eight-digit) in length, the
player truncates or shortens the information. A truncated code consists of an
Upper Byte from the first code and a Lower Byte from the second code. The
player creates a Returning Code or Double Code from these two bytes.
Once the player returns an Input Code, a FFFFh Code (no reactions from the
remote control) repeats until a new code is sent from the remote control.
