Note The TABnOVF0 and TABnOVF1 flags are set on the internal RAM by software.
<1> Read the TABnCCR0 register (setting of the default value of the TIBn0 pin input).
<2> Read the TABnCCR1 register (setting of the default value of the TIBn1 pin input).
<3> An overflow occurs. Set the TABnOVF0 and TABnOVF1 flags to 1 in the overflow interrupt
<4> Read the TABnCCR0 register.
<5> Read the TABnCCR1 register.
<6> Same as <3>

servicing, and clear the overflow flag to 0.
Read the TABnOVF0 flag. If the TABnOVF0 flag is 1, clear it to 0.
Because the TABnOVF0 flag is 1, the pulse width can be calculated by (10000H + D
Read the TABnOVF1 flag. If the TABnOVF1 flag is 1, clear it to 0 (the TABnOVF0 flag is cleared in
<4>, and the TABnOVF1 flag remains 1).
Because the TABnOVF1 flag is 1, the pulse width can be calculated by (10000H + D
