Description
Timer Counter (Default: 0x00000000)
This Register is a 32-bit counter.
Read operation on this register returns the counter value.
Write operation to this register force the counter value to the write data.
The write data should be less than the value of the register TMCPRAn and
the timer operates normally except starting counter value.
If this write data value is greater or equal to the value of TMCPRAn, the result
is undefined.
