STROBE – Event Strobe Register
DATA – Event Data Register
Table 6-6.
If the STROBE register location is written, each event channel will be set according to the
STROBE[n] and corresponding DATA[n] bit setting if any are unequal to zero.
A single event lasting for one peripheral clock cycle will be generated.
This register contains the data value when manually generating a data event. This register must
be written before the STROBE register, for details
page 74.
