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 03D716) 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 03D716 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 1.17.1 shows the performance of the A-D converter. Figure 1.17.1 shows the block diagram of the
A-D converter, and Figures 1.17.2 and 1.17.3 show the A-D converter-related registers.
Note 1: Does not depend on use of sample and hold function.
Note 2: Divide the frequency if f(XIN) exceeds 10MHZ, and make
φAD frequency equal to or less than 10MHz.
Without sample and hold function, set the
φAD frequency to 250kHZ min.
With the sample and hold function, set the
φAD frequency to 1MHZ min.
