18.3

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.
