The GTM transceiver allows you to reset the entire TX completely at any time by sending GTTXRESET an active-High pulse. These conditions must be met when using GTTXRESET:

  1. TXRESETMODE must be set to sequential mode.
  2. All TXPMARESETMASK, and TXPCSRESETMASK bits should be held High during the reset sequence before TXRESETDONE is detected High.
  3. The associated PLL must indicate locked.
  4. The guideline for this asynchronous GTTXRESET pulse width is one period of the reference clock.
