Register T12 represents the counting value of Timer T12. It can only be written while
Timer T12 is stopped. Write actions while T12 is running are not taken into account.
Register T12 can always be read by software.

Description
T12 Count Value
Represents the 16-bit count value of Timer T12
Register T12PR contains the period value for Timer T12. The period value is compared
to the actual count value of T12 and the resulting actions depend on the defined counting
rules.

Description
T12 Period Value
When T12 equals value T12PV a period-match is
triggered. When reaching this value, Timer T12 is set
to zero (edge-aligned mode) or changes its count
direction to down counting (center-aligned mode).
This register has a shadow register (using the same address) and the shadow transfer
is controlled by bit STE12. A read action by SW delivers the value which is currently used
for the period compare, whereas a write action targets the shadow register. The shadow
register structure allows concurrent updating of all T12-related values.
