6.2. Dynamic Reconfiguration

The TX reconfiguration management is handled by software.

The responsibilities of software are:

  • To switch the reference clock of the fPLL over from the fixed rate clock to the TX TMDS clock. This is because the transceiver requires a clock to be present at power‑up.
  • Re-configure and reset the IOPLL to produce the correct ls_clk and vid_clk from the tx_tmds_clk.
  • Re-configure and reset the fPLL to produce the correct output serial rate.
  • Reset and re-calibrate the transceiver
  • Calculate the required oversample rate and set the OS register to communicate the required oversampling to the HDMI TX core.
