RC8650 VOICE SYNTHESIZER
RC SYSTEMS
Table 2.8. TS Pin Control
Table 2.9. Protocol Options Register Bit Definitions
Zap Commands (Z)
This command prevents the RC8650 from honoring subsequent com-
mands, causing it to read commands as they are encountered (useful
in debugging). Any pending commands in the input buffer will still
be honored. The only way to restore command recognition after the
Zap command has been issued is to write
CTRL+^
(ASCII 30) to the
RC8650 or perform a hardware reset.
Protocol Options Register (nG)
This command controls various internal RC8650 operating param-
eters. The command parameter
n
is calculated by ORing together the
individual control bits shown in Table 2.9. For example, 193G (193 =
128 + 64 + 1) disables V8600 emulation, enables all status messages
and specifies that parameters should saturate. 128G is the default
setting.
Bit POR.7 (VC) programs the RC8650 to emulate RC Systems’ original
V8600 voice synthesizer module. When this bit is set to 0 (which V8600
application programs do, as this bit was undefined in the V8600),
the overall voice speed range is reduced and the default speed is
changed from 1S to 5S, matching the characteristics of the V8600.
The serial port status messages (see Table 1.3) are also affected by
the setting of this bit.
Note
Relative parameters work differently than usual with this com-
mand. Instead of specifying a displacement from the register’s
current value, relative parameters allow you to set (“+”) and clear
(“–”) individual register bits. For example, +65G sets bits POR.0 and
POR.6; –65G clears POR.0 and POR.6.
Reinitialize (@)
This command reinitializes the RC8650 by clearing the input buffer and
restoring the voice parameters and control registers to their factory
default settings. The exception dictionary, prerecorded audio, greeting
message, baud rate, nor TS pin control setting are affected.
Stop (CTRL+X), Skip (CTRL+Y)
The Stop command stops the RC8650 and flushes its input buffer of all
text and commands. The Skip command skips to the next sentence in
the buffer. Neither command affects any of the RC8650’s settings.
Note
The format of these commands is unique in that the command
character (CTRL+A) is not used with them. The CTRL+X (ASCII 24)
and CTRL+Y (ASCII 25) characters are
written directly
to the RC8650,
which enables the RC8650 to react immediately, even if its input buf-
fer is full. To be most effective, the states of the RC8650 handshaking
signals should be ignored.
