5.2 Random Playback Function
The random playback function generates 31 random addresses correspoding to the 5 bits of the
addresses of A0, and SW3-SW0 (except ALL "L") on the IC, after which playback commences.
This means there is no external input to the A0, SW3-SW0 pins. Since the A0 pin has no internal pull-
up/pull-down resistor, permanently set to "L" or "H".
Playback will not occur if none of the 31 addresses have been assigned a phrase. Caution is advised when
creating ROM data.
For example, when four phrases, "sunny", "rainy", "cloudy", and "snowy" are to be played, set the
phrases as shown in Table 5.1 to 31 random addresses. The four phrases are then played at random
as shown below.

Random playback occurs in accordance with the timing shown in Figure 5.6. The random address
is captured at the fall of the
RND
pin, and voice playback commences. When power is turned ON,
or when
RESET
is input, the phrase at address "00001" is played while a random counter remains
initialized until random playback is initiated.
