START
<1> Count operation start flow
Initial setting of these registers is performed before
setting the TXnTMC bit to 1.
Register initial setting
TXnCTL2 register,
TXnCTL1 register,
TXnCRk register
Starts count operation
TXnTMC bit = 1
<2> Count operation stop flow
TXnTMC bit = 0
The counter is initialized and counting is stopped
by clearing the TXnTMC bit to 0.
