Description
Trigger Enable
A/D conversion is started at the falling edge and the rising
edge of the external trigger signal (ADTRG) when this bit is
set to 1.
The selection between the falling edge and rising edge of
the external trigger pin (ADTRG) conforms to the WPEG5
bit in the interrupt edge select register 2 (IEGR2)
Reserved
These bits are always read as 1.
Reserved
Do not set this bit to 1, though the bit is readable/writable.
