Note The capture interrupt signal (INTTM00n) is not generated when the reverse-phase edge of the TI00n pin
Remark n = 0:
input is selected to the valid edge of CR00n.

Note
Initial setting of these registers is performed
before setting the TMC0n3 and TMC0n2 bits.
Starts count operation
The counter is initialized and counting is stopped
by clearing the TMC0n3 and TMC0n2 bits to 00.
