Chapter 7 Digital-to-Analog Converter (DAC8B1CV1)
Conversion of the data in DACD register takes place as soon as DACE bit of DACC0 is set. The transfer
characteristic of the day module is shown in
7.5
7.5.1
The DAC8B1C module is reset on a system reset. If the system reset signal is activated, the DAC registers
are initialized to their reset state and the DAC8B1C module is powered down. This occurs as a function
of the register file initialization. If the module is performing a conversion, the current conversion is
terminated.
