[1] Set the TSTRA.CST3 and TSTRA.CST4 bits to
0 to stop operation of the timer counter (TCNT).
Specify the TWCRA register while MTU3.TCNT
and MTU4.TCNT are stopped.
[2] Read the TWCRA.WRE bit and then write 1 to
the bit to suppress the initial value output at
counter clearing.
[3] Set the TSTRA.CST3 and TSTRA.CST4 bits to
1 simultaneously to start count operation.
