A/D CONVERTER COMMANDS
ADC Control Register (n$)
The ADC Control Register controls the operation of the integrated
analog-to-digital converter. All ADC results are transferred via the
TXD pin.
The following is an overview of the ADC:
– Four channels, 8-bit resolution (±2 LSB precision)
– One-shot, continuous, single sweep, and continuous sweep
modes of operation
– Selectable software or hardware triggering
– Support for external amplification/signal conditioning of all four
ADC channels
Figure 2.2 is a functional block diagram of the ADC input stage; Figure
2.3 illustrates the ADC in operation. Table 2.12 lists the definitions of
each bit of the ADC Control Register. The default register setting is 0$.
Operation of the ADC is not mutually exclusive of other RC8650
functions. The ADC can operate concurrently with text-to-speech,
tone generation, audio playback, etc. The effective sampling rate in
continuous mode is one-tenth the serial port baud rate (e.g., 115200
baud = 11.52 ksps).
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, +34$ sets bits ADR.1 and
ADR.5; –16$ clears ADR.4.
