The D/A converter consists of two separate 8-bit R-2R ladder D/A converters.
Digital code is converted to an analog voltage when a value is written to the corresponding DAi registers
(i=0,1). The DAiE bit in the DACON register determines whether the D/A conversion result output is pro-
vided or not. Set the DAiE bit to "1" (output enabled) to disable a pull-up of a corresponding port.
Output analog voltage (
Table 19.1 lists specifications of the D/A converter. Table 19.2 lists pin setting of the DA0 and DA1 pins.
Figure 19.1 shows a block diagram of the D/A converter. Figure 19.2 shows the D/A control register. Figure
19.3 shows a D/A converter equivalent circuit.
When the D/A converter is not used, set the DAi register to "00
