Section 28 D/A Converter (DAC)
28.2
Table 28.1 summarizes the input/output pins used by the D/A converter.
Table 28.1 Pin Configuration
28.3
The D/A converter has the following registers. Refer to section 37, List of Registers, for more
details on the addresses and states of these registers in each operating mode.
• D/A data register 0 (DADR0)
• D/A data register 1 (DADR1)
• D/A control register (DACR)
28.3.1
DADR0 and DADR1 are 8-bit readable/writable registers that store data for D/A conversion.
When the D/A output enable bits (DAOE1, DAOE0) of the DA control register (DACR) are set to
1, the contents of the D/A data register are converted and output to analog output pins (DA0,
DA1). The D/A data register is initialized to H'00 at reset. Note that the D/A data register is not
initialized upon entering the software standby, module standby, or hardware standby mode.
