21. A/D Converter
The A/D converter consists of one 10-bit successive approximation A/D converter circuit with a capacitive
coupling amplifier. Pins P100 to P107, P95, and P96 also function as the analog signal input pins. The
direction registers of these pins for A/D conversion must therefore be set to input. The Vref connect bit (bit
5 at address 039716) can be used to isolate the resistance ladder of the A/D converter from the reference
voltage input pin (VREF) when the A/D converter is not used. Doing so stops any current flowing into the
resistance ladder from VREF, reducing the power dissipation. When using the A/D converter, start A/D
conversion only after setting bit 5 of 039716 to connect VREF.
The result of A/D conversion is stored in the A/D registers of the selected pins. When set to 10-bit precision,
the low 8 bits are stored in the even addresses and the high 2 bits in the odd addresses. When set to 8-bit
precision, the low 8 bits are stored in the even addresses.
Table 21.1 shows the performance of the A/D converter. Figure 21.1 shows the block diagram of the
A/D converter, and Figures 21.2 and 21.3 show the A/D converter-related registers.
Note 1: Does not depend on use of sample and hold function.
Note 2: When f(XIN) is over 10 MHz, the fAD frequency must be under 10 MHz by dividing.
Without sample and hold function, set the fAD frequency to 250kHz min.
With the sample and hold function, set the fAD frequency to 1MHz min.
