4.7.1.1
The timer T12 is used for capture/compare purposes with three independent channels.
The timer T12 is a 16-bit wide counter. Three channel registers (CC60R, CC61R,
CC62R), which are built with shadow registers (CC60SR, CC61SR, CC62SR), contain
the compare value or the captured timer value. In compare mode, the software writes to
the shadow registers and their contents are transferred simultaneously to the actual
compare registers during the T12 shadow transfer. In capture mode, the captured value
of T12 can be read from the channel registers. The period of the timer T12 is fixed by the
period register T12PR, which is also built with a shadow register.
The write access from the CPU targets the corresponding shadow registers, whereas the
read access targets the registers actually used (except for the three compare channels,
where the actual and the shadow registers can be read).
Figure 4-10
While timer T12 is running, write accesses to register T12 are not taken into account. If
the timer T12 is stopped and the dead-time counters are 0, write actions to register T12
are immediately taken into account.
