Register 86: Ethernet MAC Software Reset (SREMAC), offset 0x59C
The SREMAC register provides software the capability to reset the available Ethernet MAC module.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SREMAC register. While the SREMAC bit is 1, the peripheral
is held in reset.
2. Software completes the reset process by clearing the SREMAC bit.
There may be latency from the clearing of the SREMAC bit to when the peripheral is ready for use.
Software should check the corresponding PREMAC bit to verify that the Ethernet MAC Module
registers are ready to be accessed.
Important: This register should be used to reset the Ethernet controller MAC 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.
