Reg. 110 (0x6E) Bits[7:5] = 001 for EEE, Reg. 110 Bits[3:0] = 0xn, n = 1-4 for the Indirect Port Register,
Reg. 111 (0x6F) Bits[7:0] = Offset to access the Indirect Byte Register 0xA0.

15 - 0 EEE Wakeup
Error
Counter
This count is incremented by one whenever a
wakeup from LPI to Idle state is longer than the
Wake-Up error threshold time specified in EEE
Global Register 4. The default of Wake-Up error
threshold time is 20.5 µs. This register is read-
cleared.
