Note The overflow counter is set arbitrarily by software on the internal RAM.
<1> Read the TAAnCCRm register (setting of the default value of the TIAAnm pin input).
<2> An overflow occurs. Increment the overflow counter and clear the overflow flag to 0 in the overflow
<3> An overflow occurs a second time. Increment (+1) the overflow counter and clear the overflow flag
<4> Read the TAAnCCRm register.

Read the overflow counter.
→ When the overflow counter is “N”, the pulse width can be calculated by (N × 10000H + D
Clear the overflow counter (0H).
