Register 78: Ethernet PHY Software Reset (SREPHY), offset 0x530
The SREPHY register provides software the capability to reset the available PHY module.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SREPHY register. While the SREPHY bit is 1, the peripheral
is held in reset.
2. Software completes the reset process by clearing the SREPHY bit.
There may be latency from the clearing of the SREPHY bit to when the peripheral is ready for use.
Software should check the corresponding PREPHY bit to verify that the EPHY Module registers are
ready to be accessed.
Important: This register should be used to reset the Ethernet PHY module.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
