This register is corresponding to each width regardless of H and L width, the pulse which exceeds
the upper value is measured and the UPINT bit of PWCC2 register is set. When this register
exceeds the counter value, the count is continued and is not stopped. Therefore the initial value
of this register is undefined, writing 1 to the UPINTE bit of PWCC2 register, and write the upper
value before compare it.
