A-D CONVERTER
The 4512 Group has a built-in A-D conversion circuit that performs
conversion by 10-bit successive comparison method. Table 14
shows the characteristics of this A-D converter. This A-D converter
can also be used as an 8-bit comparator to compare analog volt-
ages input from the analog input pin with preset values.

Notes 1:
This switch is turned ON only when A-D converter is operating and generates the comparison voltage.
2:
Writing/reading data to the comparator register is possible only in the comparator mode (Q2
3
=1).
The value of the comparator register is retained even when the mode is switched to the A-D conversion
mode (Q2
3
=0) because it is separated from the successive comparison register (AD). Also, the resolution in
the comparator mode is 8 bits because the comparator register consists of 8 bits.
