18.3 Register Descriptions
The D/A converter has the following registers.
• D/A data register 0 (DADR0)
*
• D/A data register 1 (DADR1)
*
• D/A data register 2 (DADR2)
• D/A data register 3 (DADR3)
• D/A data register 4 (DADR4)
*
• D/A data register 5 (DADR5)
*
• D/A control register 01 (DACR01)
*
• D/A control register 23 (DACR23)
• D/A control register 45 (DACR45)
*
Note: * Not supported by the H8S/2375, H8S/2375R, H8S/2373, and H8S/2373R.
18.3.1 D/A Data Registers 0 to 5 (DADR0 to DADR5)
DADR0 to DADR5 are 8-bit readable/writable registers that store data for conversion.
Whenever output is enabled, the values in DADR are converted and output to the analog output
pins.
When the H8S/2375, H8S/2375R, H8S/2373, or H8S/2373R is in use, the registers which are not
supported must not be accessed.
18.3.2 D/A Control Registers 01, 23, and 45 (DACR01, DACR23, DACR45)
DACR01, DACR23, and DACR45 control the operation of the D/A converter. DACR01,
DACR23, and DACR45 control the operation of channels 0 and 1, channels 2 and 3, and channels
4 and 5, respectively.
