Table 15.1 A/D Converter Performance
The microcomputer contains one A/D converter circuit based on 10-bit successive approximation method
configured with a capacitive-coupling amplifier. The analog inputs share the pins with P10
AN
shares the pin with P1
bits are set to “0” (input mode). Note that P1
the 80-pin package.
When not using the A/D converter, set the VCUT bit to “0” (Vref unconnected), so that no current will flow
from the Vref pin into the resistor ladder, helping to reduce the power consumption of the chip.
The A/D conversion result is stored in the ADi register bits for AN
Table 15.1 shows the A/D converter performance. Figure 15.1 shows the A/D converter block diagram
and Figures 15.2 to 15.4 show the A/D converter associated with registers.
