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. Nothing is done by software.
<4> Read the TQ0CCR0 register.
<5> Read the TQ0CCR1 register.
<6> Same as <3>
TQ0CCR0 register
TQ0CCR1 register
Example when two capture registers are used (without using overflow interrupt)
INTTQ0OV signal
TQ0OVF0 flag
TQ0OVF1 flag
Read the overflow flag. If the overflow flag is 1, set only the TQ0OVF1 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 TQ0OVF1 flag. If the TQ0OVF1 flag is 1, clear it to 0.
Because the TQ0OVF1 flag is 1, the pulse width can be calculated by (10000H + D
(correct).
