Note The TTmOVF0 and TTmOVF1 flags are set on the internal RAM by software.
<1> Read the TTmCCR0 register (setting of the default value of the TITm0 pin input).
<2> Read the TTmCCR1 register (setting of the default value of the TITm1 pin input).
<3> An overflow occurs. Nothing is done by software.
<4> Read the TTmCCR0 register.
<5> Read the TTmCCR1 register.
<6> Same as <3>
Remark
TTmCCR0 register
TTmCCR1 register
INTTTIOVm signal
Example when two capture registers are used (without using overflow interrupt)
TTmOVF0 flag
TTmOVF1 flag
Read the overflow flag. If the overflow flag is 1, set only the TTmOVF1 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 TTmOVF1 flag. If the TTmOVF1 flag is 1, clear it to 0.
Because the TTmOVF1 flag is 1, the pulse width can be calculated by (10000H + D
(correct).
