A-D CONVERTER
[A-D Conversion Register (AD)] 003516
The A-D conversion register is a read-only register that contains
the result of an A-D conversion. During A-D conversion, do not
read this register.
[A-D Control Register (ADCON)] 003416
The A-D control register controls the A-D conversion process. Bits
0 to 2 are analog input pin selection bits. Bit 3 is an A-D conver-
sion completion bit and “0” during A-D conversion, then changes
to “1” when the A-D conversion is completed. Writing “0” to this bit
starts the A-D conversion. Bit 4 controls the transistor which
breaks the through current of the resistor ladder. When bit 5, which
is the AD external trigger valid bit, is set to “1”, A-D conversion is
started even by a rising edge or falling edge of an ADT input. Set
ports which share with ADT pins to input when using an A-D exter-
nal trigger.
[Comparison Voltage Generator]
The comparison voltage generator divides the voltage between
AVSS and VREF, and outputs the divided voltages.
[Channel Selector]
The channel selector selects one of the input ports P67/AN7–P60/
AN0, and inputs it to the comparator.
[Comparator and Control Circuit]
The comparator and control circuit compares an analog input volt-
age with the comparison voltage and stores the result in the A-D
conversion register. When an A-D conversion is completed, the
control circuit sets the AD conversion completion bit and the AD
interrupt request bit to “1”.
Note that the comparator is constructed linked to a capacitor, so
set f(XIN) to at least 500 kHz during A-D conversion.
Use a clock divided the main clock XIN as the internal clock
φ.
