Note The TPkOVF0 and TPkOVF1 flags are set on the internal RAM by software.
<1> Read the TPkCCR0 register (setting of the default value of the TIPk0 pin input).
<2> Read the TPkCCR1 register (setting of the default value of the TIPk1 pin input).
<3> An overflow occurs. Nothing is done by software.
<4> Read the TPkCCR0 register.
<5> Read the TPkCCR1 register.
<6> Same as <3>
Remark
TPkCCR0 register
TPkCCR1 register
Example when two capture registers are used (without using overflow interrupt)
INTTPkOV signal
TPkOVF0 flag
TPkOVF1 flag
Read the overflow flag. If the overflow flag is 1, set only the TPkOVF1 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 TPkOVF1 flag. If the TPkOVF1 flag is 1, clear it to 0.
Because the TPkOVF1 flag is 1, the pulse width can be calculated by (10000H + D
(correct).
