XTIMER peripheral (trigger for ADC channel injection)

This new peripheral is dedicated for the Channel Injection Mode of the A/D converter. This

mode injects a channel into a running sequence without disturbing this sequence. The

peripheral event controller stores the conversion results in memory without entering and

exiting interrupt routines for each data transfer.

A channel injection can be triggered by an event on Capture/Compare CC31 (Port P7.7) of

the CAPCOM2 unit.

The dedicated output XADCINJ of the XTIMER must be connected externally on the input

P7.7/CC31.
