CONVERTERS WITH INTERNAL REFERENCE AND POWER DOWN

APPLICATION INFORMATION
software
In the following example, the code generates a waveform at 20 KSPS with 32 samples stored in a table within
the program memory space of the microcontroller.
The waveform data is located in the program memory space at segment SINTBL beginning with the MSW of
the first 16-bit word (the 4 MSBs are ignored), followed by the LSW. Two bytes are required for each DAC word
(the table is not shown in the code example).
The program consists of two parts:
A main routine, which is executed after reset and which initializes the timer and the interrupt system of the
microcontroller.
An interrupt service routine, which reads a new value from the waveform table and writes it to the DAC.
