18.3 Register Description
The D/A converter has the following registers. For details on the module stop control register,
refer to section 24.1.2, Module Stop Control Registers A to C (MSTPCRA to MSTPCRC).
• D/A data register 0 (DADR0)
• D/A data register 1 (DADR1)
• D/A control register (DACR)
18.3.1 D/A Data Registers 0 and 1 (DADR0 and DADR1)
DADR0 and DADR1 are 8-bit readable/writable registers that store data for D/A conversion.
When analog output is permitted, D/A data register contents are converted and output to analog
output pins.
