Table 4. Control Registers and Bits for Wake-Up Event of Power Management
If this bit is set, it indicates that the KSZ8841-PMQL support D1 power state. The
value of this bit loaded from the D1_SUP bit in the EEPROM 0x6 word. (This bit is
0 only if without EEPROM).
If this bit is set, the KSZ8841-PMQL can assert the PME_N pin. Otherwise,
assertion of the PME_N pin is disabled. This bit is cleared on power-up reset only
and is not modified by either hardware or software reset.
This field is used to set the current power state of the system and to assert a
power management event. The definitions of the field values are:
0: D0
1: D1
2: D2
3: D3 (hot)
This field gets a value of 0 after power up and reset.
