TIMCTRL – DAC Timing Control Register
• Bit 0 - LEFTADJ: DAC Left-Adjust Value
If this bit is set, CH0DATA and CH1DATA are left-adjusted.
• Bits 7:3 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bits 2:1 - EVSEL[2:0]: DAC Event Channel Input Selection
These bits define which channel from the Event System that is used for triggering a DAC
conversion.
Table 26-3
Table 26-3.
• Bit 7 - Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bits 6:4 - [2:0]: - CONINTVAL - DAC Conversion Interval
These bits control the minimum interval between two successive conversions. The interval must
be set relative to the Peripheral clock (clk
the result from the previous conversion has settled. The DAC Conversion Interval should never
be set lower than 1 µs during single channel operation, and not lower than 1.5 µs during dual
channel (S/H) operation.
