Note The TAAmOVF0 and TAAmOVF1 flags are set on the internal RAM by software.
<1> Read the TAAmCCR0 register (setting of the default value of the TIAm0 pin input).
<2> Read the TAAmCCR1 register (setting of the default value of the TIAm1 pin input).
<3> An overflow occurs. Set the TAAmOVF0 and TAAmOVF1 flags to 1 in the overflow interrupt
<4> Read the TAAmCCR0 register.
<5> Read the TAAmCCR1 register.
<6> Same as <3>

servicing, and clear the overflow flag to 0.
Read the TAAmOVF0 flag. If the TAAmOVF0 flag is 1, clear it to 0.
Because the TAAmOVF0 flag is 1, the pulse width can be calculated by (10000H + D
Read the TAAmOVF1 flag. If the TAAmOVF1 flag is 1, clear it to 0 (the TAAmOVF0 flag is cleared
in <4>, and the TAAmOVF1 flag remains 1).
Because the TAAmOVF1 flag is 1, the pulse width can be calculated by (10000H + D
(correct).
