A-D CONVERTER
The 4513/4514 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 voltages input from the analog input pin with preset val-
ues.

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 (Q23=1).
The value of the comparator register is retained even when the mode is switched to the A-D conversion
mode (Q23=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.
3: The 4513 Group does not have ports P40/AIN4–P43/AIN7 and the IAP4 and OP4A instructions.
