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. Set the TPnOVF0 and TPnOVF1 flags to 1 in the overflow interrupt servicing,
<4> Read the TPnCCR0 register.
<5> Read the TPnCCR1 register.
<6> Same as <3>
TPnCCR0 register
TPnCCR1 register
and clear the overflow flag to 0.
Read the TPnOVF0 flag. If the TPnOVF0 flag is 1, clear it to 0.
Because the TPnOVF0 flag is 1, the pulse width can be calculated by (10000H + D
Read the TPnOVF1 flag. If the TPnOVF1 flag is 1, clear it to 0 (the TPnOVF0 flag is cleared in <4>,
and the TPnOVF1 flag remains 1).
Because the TPnOVF1 flag is 1, the pulse width can be calculated by (10000H + D
(correct).
