A-D CONVERTER
[A-D Conversion Registers (ADL, ADH)]
003516, 003616
The A-D conversion registers are read-only registers that store the
result of an A-D conversion. Do not read these registers during an
A-D conversion
[AD Control Register (ADCON)] 003416
The AD control register controls the A-D conversion process. Bits
0 to 2 select a specific analog input pin. Bit 4 indicates the
completion of an A-D conversion. The value of this bit remains at
“0” during an A-D conversion and changes to “1” when an A-D
conversion ends. Writing “0” to this bit starts the A-D conversion.
Comparison Voltage Generator
The comparison voltage generator divides the voltage between
AVSS and VREF into 1024 and outputs the divided voltages.
Channel Selector
The channel selector selects one of ports P30/AN0 to P37/AN7 and
inputs the voltage to the comparator.
Comparator and Control Circuit
The comparator and control circuit compare an analog input volt-
age with the comparison voltage, and the result is stored in the
A-D conversion registers. When an A-D conversion is completed,
the control circuit sets the A-D conversion completion bit and the
A-D interrupt request bit to “1”.
Note that because the comparator consists of a capacitor cou-
pling, set f(XIN) to 500 kHz or more during an A-D conversion.
When the A-D converter is operated at low-speed mode, f(XIN)
and f(XCIN) do not have the lower limit of frequency, because of
the A-D converter has a built-in self-oscillation circuit.
