Table 3.2 Random Playback Address
For a random address, 15 phrases can be set for each logical condition of addresses A2 and A1
(i.e., "00", "01", "10", and "11").
In random playback, the four logic states ("000000", "010000", "100000" and "110000") in user-
specified phrases cannot be used. Take it into consideration when creating ROM data.
A random address is set by the "H" level time of the
RND
pin, so if the same pulse width is input
by microcontroller, the random address fixed time becomes constant, and a random phrase may
not be played under these conditions. The random address fixed time must be inconsistent in
order to produce random playback.
