Sequential Mode
Support play up to 256 voice section sequentially by 1 TG pin. It also provides a BUSY output, the
BUSY pin will output VIH when voice playing.
When TG pin rising edge, chip will play voice. Rising edge again, then play next voice section.
When last voice section is played, chip will return to voice section 0.

CPU Serial Mode
The CPU serial mode is designed for CPU interface. The host CPU can send data to control
aMTPxxM. Serial Clock and Serial Data are used to input section number. BUSY is output from the
chip to the host CPU for feedback response. Maximum 256 voice section are available.

User can start to play the voice or pause current voice by Play/Pause pin, and forward or backward
play by Forward pin or Backward pin, up to 256 Voice Sections.
User can enable repeat function by Repeat Enable pin. When repeat enable, it will loop play the
current voice section by Repeat Ranges pin is VIL; It will loop play all the voice section sequentially
by Repeat Range pin is VIH.

RAMP UP / RAPM DOWN
When playback in DAC, Ramp Up /Ramp Down will enabled. This function eliminates the ‘POP’ noise at
the begin and end of voice playback.
Fig. 1 Ramp-up-down Enable
VOICE TABLE
One voice section can include many voice slices. User can use voice slices to save memory usage. For
example, we have 3 voice file store in the memory:
File 1: “How are You?”
File 2: Sound Effect
File 3: Music
Voice slices are grouped together using Voice Table to form Voice Section for playback:
