Function Description
Mode selection Low voltage detect Key Control Mode PA0: Ring Detect When an incoming 13Hz~90Hz ring signal is detected after a period of 200ms, the music will automatically start playing. When the incoming ring signal stops, after a period of 6 seconds the music will stop playing. This line detects the on/off hook condition of the telephone. Only when the telephone is in an on-hook condition, can the music be chosen and played. If the handset is lifted to talk, the music will stop playing and the HOLD key will be effective. This key chooses and plays one of the 36 stored musical melodies. When the key is pressed the next melody in the list will be selected and played. When the HOLD key is pressed, the telephone hold function will be activated and when an incoming ring signal is detected the music will be played. If this key is pressed during a phone conversation the phone will be put on hold and the caller can listen to the music while waiting. If, when the music is playing, the handset is lifted, the music will immediately stop playing. After this happens the HOLD function will have no effect for a period of 2 seconds. Controls the music volume in 8 discrete steps. Each time the key is pressed the volume will reduce one step at a time until the lowest volume is reached. When the lowest volume is reached, the next key press will return the volume to its maximum level.

Note:
50ms after power up, the device will be ready to communicate with the external CPU using the CLK and DATA lines. Communication via the CLK and DATA lines is conducted in a simple manner. The device will obtain its data on the high going edge of the CLK line. If the device does not receive a complete byte within 50ms then the present byte will be discarded and the next byte will then be received. Even-parity is used for data checking. For the previous 8-bits, if the total number of 1s is odd then the parity bit is set to 1, otherwise it is set to 0. If the parity is incorrect then the byte will be discarded.
Data Type (Command) 00H~23H 30H~53H 5FH 60H~6FH This command will select and play one of the 36 stored musical melodies (play once). This command will select and play one of the 36 stored musical melodies (repeatedly once). Stop play 16 level volume control, 60H refers to highest volume (power on default 60H)
