Port x PHY Interrupt Source Flags Register (PHY_INTERRUPT_SOURCE_x)
This read-only register is used to determine to source of various Port x PHY interrupts. All interrupt
source bits in this register are read-only and latch high upon detection of the corresponding interrupt
(if enabled). A read of this register clears the interrupts. These interrupts are enabled or masked via
the
Port x PHY Interrupt Mask Register
