Register TCTR2 controls the single-shot and the synchronization functionality of both
timers T12 and T13. Both timers can run in single-shot mode. In this mode they stop their
counting sequence automatically after one counting period with a count value of zero.
The single-shot mode and the synchronization feature of T13 to T12 allows the
generation of events with a programmable delay after well-defined PWM actions of T12.
For example, this feature can be used to trigger AD conversions after a specified delay
(to avoid problems due to switching noise) synchronously to a PWM event.

Bits Type Description
0
rw Timer T12 Single Shot Control
This bit controls the single shot-mode of T12.
0 The single-shot mode is disabled, no HW action
on T12R.
1 The single shot mode is enabled, the bit T12R is
reset by HW if
- T12 reaches its period value in edge-aligned
mode
- T12 reaches the value 1 while down counting
in center-aligned mode.
In parallel to the reset action of bit T12R, the bits
CC6xST (x=0, 1, 2) are reset.
1
rw Timer T13 Single Shot Control
This bit controls the single shot-mode of T13.
0 No HW action on T13R
1 The single-shot mode is enabled, the bit T13R is
reset by HW if T13 reaches its period value.
In parallel to the reset action of bit T13R, the bit
CC63ST is reset.
