Note The TQ0OVF0 and TQ0OVF1 flags are set on the internal RAM by software.
<1> Read the TQ0CCR0 register (setting of the default value of the TIQ00 pin input).
<2> Read the TQ0CCR1 register (setting of the default value of the TIQ01 pin input).
<3> An overflow occurs.
<4> Read the TQ0CCR0 register.
<5> Read the TQ0CCR1 register.
<6> Same as <3>

servicing, and clear the overflow flag to 0.
Read the TQ0OVF0 flag. If the TQ0OVF0 flag is 1, clear it to 0.
Because the TQ0OVF0 flag is 1, the pulse width can be calculated by (10000H + D
Read the TQ0OVF1 flag. If the TQ0OVF1 flag is 1, clear it to 0 (the TQ0OVF0 flag is cleared in
<4>, and the TQ0OVF1 flag remains 1).
Because the TQ0OVF1 flag is 1, the pulse width can be calculated by (10000H + D
