START Command Input Timing for Continuous Playback

The diagram below shows the START command input timing in cases where one phrase is played and then the
next phrase is played in succession.

As shown in the diagram above, if performing continuous playback, input the START command for the second
phrase within 10 ms (t

cm

) after the NCR signal on the target channel goes “H”. Input the following START

command after checking that playback is completed by the RDSTAT command, when it is not continuous
playback.
