and the conversion result is output.
The operation example concerns D/A conversion on channel 2. Figure 18.4 shows the timing of
this operation.
[1] Write the conversion data to DADR2.
[2] Set the DAOE2 bit in DACR23 to 1. D/A conversion is started. The conversion result is output
[3] If DADR2 is written to again, the conversion is immediately started. The conversion result is
[4] If the DAOE2 bit is cleared to 0, analog output is disabled.
Notes: 1. Two channels are available for the H8S/2375, H8S/2375R, H8S/2373, and H8S/2373R.
