Section 15 D/A Converter
15.2
15.2.1
The D/A data registers (DADR0 and DADR1) are 8-bit readable/writable registers that store the
data to be converted. When analog output is enabled, the D/A data register values are constantly
converted and output at the analog output pins.
The D/A data registers are initialized to H'00 by a reset and in standby mode.
When the DASTE bit is set to 1 in the D/A standby control register (DASTCR), the D/A registers
are not initialized in software standby mode.
15.2.2
DACR is an 8-bit readable/writable register that controls the operation of the D/A converter.
DACR is initialized to H'1F by a reset and in standby mode.
When the DASTE bit is set to 1 in the D/A standby control register (DASTCR), the D/A registers
are not initialized in software standby mode.
