Extended PHY Control 4
The register at address 23E consists of the fourth set bits that control various aspects
of inline powering and the CRC error counter in the VSC8641 device.
Extended PHY Control 4, Address 23E (0x17)
Note Bits 9:8 are only valid if bit 10 is set.
Reserved Extended Registers
The bits in the extended register page space at addresses 24E, 25E, and 26E (0x18,
0x19, and 0x1A, respectively) are reserved.

Description
PHY address; latched on reset.
This is a sticky bit.
1 = Enabled.
00 = Searching for devices.
01 = Device found; requires inline power.
10 = Device found; does not require
inline power.
11 = Reserved.
This is a self-clearing bit.
CRC error counter for the Ethernet packet
generator. The value saturates at 0xFF
and subsequently clears when read and
restarts count.
