2.4.3 PF_POWER_INIT

The PF_POWER_INIT block ensures the device is turned on systematically. The process of turning on the device includes following three steps:

  1. Power-on reset
  2. Programmed device boot
  3. Design initialization
During design initialization, the transceiver configuration is initialized using the data stored in the non-volatile memory. The output of the PF_POWER_INIT block is ANDed with the resets used in the design to reset entire logic. The following table lists the reset signals.
