msm9811 Oki Semiconductor, msm9811 Datasheet - Page 34

• Manufacturer Part Number: msm9811
• Description: 4-channel Mixing Oki Adpcm Type Voice Synthesis Lsi
• Manufacturer: Oki Semiconductor

As Figure 7 shows, CS and WR pulses are input 7 times when CMD is in “H” status, to input data to the TMP1 to
TMP7 registers. The LSI increments the registers at the rise of the WR pulse when CMD is “H”. CMD must not
be “L” while inputting data. When CMD becomes “L” while inputting data, the increment of registers is cleared.
Table 5 shows the configuration of data to be input to TMP1 to TMP7 registers.
Input the start address of voice data to TMP1 to TMP3 registers. Input the stop address of voice data to TMP4 to
TMP6 registers. Input the playback system and sampling frequency to the TMP7 register.
Table 6 shows the input data configuration of the playback system and sampling frequency.
