Figure 8-62. Example of Resolving Problem When Two or More Capture Registers Are Used Without Using
Note The TQ0OVF0 and TQ0OVF1 flags are set on the internal RAM by software.
<1> The TQ0CCR0 register is read (the default value of the TIQ00 pin input is set).
<2> The TQ0CCR1 register is read (the default value of the TIQ01 pin input is set).
<3> An overflow occurs. There is no software processing.
<4> The TQ0CCR0 register is read.
<5> The TQ0CCR1 register is read.
<6> Same as <3>.

INTTQ0OV signal
TQ0OVF0 flag
TQ0OVF1 flag
The TQ0OVF bit is read. The TQ0OVF bit is 1, so only the TQ0OVF1 flag is set to 1; the TQ0OVF
bit is cleared to 0.
Because the TQ0OVF bit is 1, the pulse width can be calculated by (10000H + D
The TQ0OVF bit is read. The TQ0OVF bit was cleared to 0 in <4>, so 0 is read.
The TQ0OVF1 flag is read. The TQ0OVF1 flag is 1, so it is cleared to 0.
Because the TQ0OVF1 flag was 1, the pulse width can be calculated by (10000H + D
(correct).
