Input Capture/Output Compare “x” Interrupt Enable — The bits in TIE correspond bit-for-bit with the bits in<br />

the TFLG1 status register. If cleared, the corresponding flag is disabled from causing a hardware interrupt. If set,<br />

the corresponding flag is enabled to cause a interrupt.<br />
