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.
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 9-9 shows the
input data configuration of the playback system and sampling frequency.
As Figure 9-4 shows, CS and WR pulses are input 7 times when CMD is in “H” status, to input
Table 9-8 shows the configuration of data to be input to TMP1 to TMP7 registers.
