Note:
A playback sequence starts with a command with LOAD set at 1, and a definition of a PHRASE NUMBER. Status
monitoring can be done by issuing command with LOAD set at 0. When READY = 1 is detected, a new phrase can be
loaded. To play a sequence of phrases, a new command with LOAD bit set at 1 should be issued after n frames (n=0..X)
from the moment READY bit is detected as 1. This will introduce n frame delays between the phrases. The monitoring
commands (bit LOAD = 0) may have any number in the PHRASE NUMBER field (for example 0 or the next phrase number
to be played). The new phrase number will not be accepted until READ bit has become 1.
END OF PLAY bit indicates that the last frame is going to be played. An IDLE command ends the mode.

SET SECTOR command can be sent any time during phrase playback instead of monitoring command. The playback will
not be interrupted. The D6571E will return status of the monitoring command. The next phrase will be loaded (by the
command with LOAD bit = 1) from the newly defined sector. Sector remains active until another SET SECTOR command is
issued. By default SECTOR 0 is active.
SET SECTOR command can be sent from Idle mode. In this case the D6571E activates a new sector, returns echo of the
command in the status word, and remains in Idle mode.
