A-D Converter
The functional blocks of the A-D converter are described below.
[A-D conversion register]
The A-D conversion register is a read-only register that stores the
result of an A-D conversion. When reading this register during an
A-D conversion, the previous conversion result is read.
[AD/DA control register]
The AD/DA control register controls the A-D conversion process.
Bits 0 to 2 select a specific analog input pin. Bit 3 signals 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.
Bits 6 and 7 are used to control the output of the D-A converter.
[Comparison voltage generator]
The comparison voltage generator divides the voltage between
AVSS and VREF into 256, and outputs the divided voltages.
[Channel selector]
The channel selector selects one of the ports P60/AN0 to P67/AN7,
and inputs the voltage to the comparator.

[Comparator and Control circuit]
The comparator and control circuit compares an analog input volt-
age with the comparison voltage, then stores the result in the A-D
conversion register. When an A-D conversion is complete, 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 500 kHz or more during an A-D conversion.
