Table 26-4
for longer conversion intervals during dual channel operation, a 50% increase in the number
peripheral clock cycles is automatically added.
Table 26-4.
The number of clock cycles selected multiplied with the period of the Peripheral clock gives the
minimum DAC conversion internal.
• Bits 3:0 - REFRESH[3:0]: DAC Channel Refresh Timing Control
These bits control time interval between each time a channel is refreshed in dual channel (S/H)
mode. The interval must be set relative to the Peripheral clock to avoid loosing accuracy of the
converted value.
