CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (A/D Converter)
(2) Oscillation circuit
The CR oscillation circuit is designed so that either the
reference resistance side or the sensor side can be oper-
ated independently by the oscillation control circuit.
A/D conversion begins when "1" is written in the ADRUN
register (0F1H D0). At the same time, the oscillation
circuit also turns on. At first, the circuit of the reference
resistance side (RS) is operated by the oscillation control
circuit. Then, the circuit of the sensor side (TH1 or TH2)
turns on when counting by the oscillation clock of the
reference resistance is terminated.
TH1 or TH2 is controlled by the CHTH register (0F1H D3).
Each circuit performs the same oscillating operation as
follows (in this example, CHTH = "0", TH1 is selected):
The Tr1 (Tr2) turns on first, and the condenser connected
between the CS and VSS terminals is charged through the
reference resistance (sensor). If the voltage level of the CS
terminal decreases, the Tr1 (Tr2) turns off and the Tr3
turns on. As a result, the condenser becomes discharged,
and oscillation is performed according to CR time con-
stant. The time constant changes as the sensor resist-
ance value fluctuates, producing a difference from the
oscillation frequency of the reference resistance.
Oscillation waveforms are shaped by the Schmitt trigger
and transmitted to counter. The clock transmitted to the
counter is also output from the ADOUT terminal. As a
result, oscillation frequency can be identified by the
oscilloscope. Since this monitor has no effect on oscilla-
tion frequency, it can be used to adjust CR oscillation
frequency.
Oscillation waveforms and waveforms output from the
ADOUT terminal are shown in Figure 4.8.2.
