Note The TPnOVF0 and TPnOVF1 flags are set on the internal RAM by software.
<1> Read the TPnCCR0 register (setting of the default value of the TIPn0 pin input).
<2> Read the TPnCCR1 register (setting of the default value of the TIPn1 pin input).
<3> An overflow occurs. Nothing is done by software.
<4> Read the TPnCCR0 register.
<5> Read the TPnCCR1 register.
<6> Same as <3>
Read the overflow flag. If the overflow flag is 1, set only the TPnOVF1 flag to 1, and clear the overflow
flag to 0.
Because the overflow flag is 1, the pulse width can be calculated by (10000H + D
Read the overflow flag. Because the overflow flag is cleared in <4>, 0 is read.
Read the TPnOVF1 flag. If the TPnOVF1 flag is 1, clear it to 0.
Because the TPnOVF1 flag is 1, the pulse width can be calculated by (10000H + D
