RC8650 VOICE SYNTHESIZER
RC SYSTEMS
The sleep timer is stopped and reset whenever the RC8650 is active,
and begins running when the RC8650 enters Idle mode. In this way,
the RC8650 will not shut itself down during normal use, as long as
the programmed timer interval is longer than the maximum time the
RC8650 is inactive.
The command parameter
n
determines when Standby mode will be
entered. You can place the RC8650 in Standby mode immediately,
program the sleep timer to any of 15 ten-minute intervals (10 to 150
minutes), or disable the sleep timer altogether (Table 2.6).
Note that the delay interval is simply
n
x 10 minutes for 0 <
n
< 16. OR-
ing 10h to these values (16 <
n
< 32) also enables the reminder tone,
which sounds at the end of each ten minute interval. Programming
n
= 0 disables the sleep timer, which is the default setting. Setting
n
=
16 forces the RC8650 to enter Standby mode as soon as all output
has ceased.
If the sleep timer is allowed to expire, the RC8650 will emit the ASCII
character “p” from the TXD pin and the STBY status flag will be set to
1, just before entering Standby mode. This enables the host to detect
that the RC8650 has entered Standby mode.
Once the RC8650 has entered Standby mode, it can be re-awakened
only by a hardware reset or by driving the STBY# pin low for 250 ns or
longer, then High again. All of the RC8650 handshake signals (BUSY,
CTS#, and RDY#) are forced to their “not ready” states while the
RC8650 is in Standby.
Index Marker (nI)
Index markers are nonspeaking “bookmarks” that can be used to keep
track of where the RC8650 is reading within a passage of text. The
parameter
n
is any number between 0 and 99; thus, up to 100 unique
markers may be active at any given time.
When the RC8650 has spoken the text up to a marker, it transmits the
marker number to the host via the TXD pin. Note that this value is a
binary
number between 0 and 99, not a literal ASCII number string as
was used in the command to place the marker. This allows the marker
to be transmitted as a one-byte value.
There is no limitation to how many index markers can be used in a text
string. The frequency depends on the resolution required by the ap-
plication. In Text mode, for example, one marker per sentence or one
marker per word would normally be used. In Phoneme mode, markers
can be placed before each phoneme to monitor phoneme production,
which is useful for synchronizing an animated mouth with the voice.
Baud Rate (nH)
The serial port’s baud rate can be programmed to the rates listed in
Table 2.7. If included as part of the greeting message, the command
will effectively override the baud rate set by the BRS pins.
Table 2.6. Sleep Timer
Table 2.5. Timeout Delays
Table 2.7. Programmable Baud Rates
TS Pin Control (nK)
The TS pins provide talk status information for each audio channel,
which can be used to activate a transmitter, take a telephone off hook,
enable an audio power amplifier, etc., at the desired time. Each pin’s
state and polarity can be configured as shown in Table 2.8. The pro-
gramming of the TS pins do not affect the Status Register TS flag in
any way. The default setting is 1K.
If a TS pin is programmed High or Low, it will remain so until changed
otherwise. This feature can be used to activate a transmitter, for ex-
ample, before speech output has begun. In the automatic mode, the
TS pin is asserted as soon as output begins; it will return to its false
state when all output has ceased. Note that because RC8650 com-
mands work synchronously, the TS pin will not change state until all
text and commands, up to the TS Pin Control command, have been
spoken and/or executed.
