The PHY power control module receives a power-up/power-down command input from the device general core control module. The power control module takes care to execute different stages of the PHY_TX and PHY_RX power-up/-down processes and ensures that the necessary timing intervals are applied between these stages.
Powering-up/-down the PHY_TX and PHY_RX modules is triggered through software writing corresponding power-up/down commands in the CTRL_CORE_PHY_POWER_PCIESS1 and CTRL_CORE_PHY_POWER_PCIESS2 registers of the device core control module.
