The DALA bit affects the configuration of the DAC data registers. Changing this bit affects the DAC output on the next DACH writing. • Bit 1 – DAOE: Digital to Analog Output Enable bit Set this bit to output the conversion result on D2A, Clear it to use the DAC internally. • Bit 0 – DAEN: Digital to Analog Enable bit Set this bit to enable the DAC, Clear it to disable the DAC. 22.4.2 Digital to Analog Converter input Register – DACH and DACL DACH and DACL registers contain the value to be converted into analog voltage. Writing the DACL register forbid the update of the input value until DACH has not been written too. So the normal way to write a 10-bit value in the DAC register is firstly to write DACL the DACH. In order to work easily with only 8 bits, there is the possibility to left adjust the input value. Like this it is sufficient to write DACH to update the DAC value. 22.4.2.1 DALA = 0 22.4.2.2 DALA = 1 1 0 0 Timer/Counter0 Overflow 1 0 1 Timer/Counter1 Compare Match B 1 1 0 Timer/Counter1 Overflow 1 1 1 Timer/Counter1 Capture Event Table 22-1.
