Description
TADCOBRA_4/TADCOBRB_4 Transfer Timing Select
Select the timing for transferring data from
TADCOBRA_4 and TADCOBRB_4 to TADCORA_4
and TADCORB_4.
For details, see table 9.29.
These bits are always read as 0. The write value should
always be 0.
Up-Count TRG4AN Enable
Enables or disables A/D converter start requests
(TRG4AN) during TCNT_4 up-count operation.
