RC8650 VOICE SYNTHESIZER
RC SYSTEMS
Figure 1.3. RS-232C Interface
Table 1.2. Baud Rate Options
High or Low period detected in the input stream. This period is as-
sumed to be the bit rate of the incoming data. In addition to the baud
rates listed in Table 1.2, auto-detect mode also supports 38400,
57600, and 115200 baud rates.
In order for the RC8650 to determine the incoming baud rate, there
must be at least one isolated “1” or “0” in the input character. The CR
character, 0Dh, is recommended for locking the baud rate. The char-
acter is not otherwise processed by the RC8650; it is discarded.
If the measured bit period is determined to be a valid baud rate, the
RC8650 acknowledges lock acquisition by transmitting the ASCII char-
acter “l” (6Ch) on the TXD pin. The baud rate will remain locked unless
changed with the baud rate command, or the RC8650 is reset.

INTERFACING THE RC8650
The RC8650 contains both asynchronous serial and 8 bit bus interfac-
es. All text, commands, tone generator data, real time audio data, etc.,
are transmitted to the RC8650 via one of these ports. For maximum
flexibility, use of the serial port is recommended whenever possible.
Not all RC8650 functions are supported through the bus interface.
In
particular, index markers, operating system updates, chipset identifi-
cation, current operating settings, and A/D conversion are only sup-
ported through the serial interface.
Serial Interface
The serial port operates with 8 data bits (LSB first), 1 or more stop bits,
no parity, and any standard baud rate between 300 and 115200 bps.
A typical RS-232C interface is shown in Figure 1.3. Note that the
MAX232A transceiver is not required if the host system’s serial port
operates at logic levels compatible with the RC8650 (0/+5 or 0/+3.3
V). The RC8650’s serial port may be connected directly to the host
system in this case.
The CTS# pin should be used to control the flow of serial data to the
RC8650. It is not necessary to check CTS# before transmitting every
byte, however. All data is routed through a high speed 16-byte buffer
within the RC8650 before being stored in the primary buffer.
CTS# may
be checked every eight bytes with no risk of data loss.
Baud rate selection
The serial port’s baud rate can be programmed using any of three
methods: pin strapping, auto-detect, and by command.
Pin strapping
sets the baud rate according to the logic levels present on the BRS

pins, as shown in Table 1.2.
Auto-detect
enables the serial port
to automatically detect the baud rate of the incoming data. The baud
rate
command
(described in Section 2) allows the baud rate to be
changed at any time, effectively overriding the first two methods. Pin
strapping cannot be used to program baud rates higher than 19200; to
do this, auto-detection or the baud rate command must be used.
The automatic baud rate detection mechanism is enabled when the

pins are all at a High logic level and the BRD pin is con-
nected to the RXD pin. The baud rate is determined by the shortest
