4.7 PME Indirect Registers
The PME registers are provided on a global and per-port basis. These registers are read/write using indirect memory
access, as shown in Table 4-20.
TABLE 4-20: PME INDIRECT REGISTERS
Address Name Description Mode Default
Global PME Control Register
Reg. 110 (0x6E) Bits[7:5] =100 for PME, Reg.110 Bits[3:0] = 0x0 for the indirect global register,
Reg. 111 (0x6F) Bits[7:0] = Offset to access the Indirect Byte Register 0xA0.
Offset: 0x00 (Bits[31:24]), 0x01 (Bits[23:16]), 0x02 (Bit[15:8]), 0x03 (Bits[7:0]).
Location: (100 PME) -> {0x0, offset} -> 0xA0 holds the data.
31 - 2 Reserved RO All ‘0’
1 PME Output
Enable
1= PME output pin is enabled.
0= PME output pin is disabled.
R/W 0
0 PME Output
Polarity
1= PME output pin is active-high.
0= PME output pin is active-low.
R/W 0
Port PME Control Status Register
Reg. 110 (0x6E) Bits[7:5] =100 for PME, Reg. 110 Bits[3:0] = 0xn for the Indirect Port Register (n = 1,2,3,4).
Reg. 111 (0x6F) Bits[7:0] = Offset to access the Indirect Byte Register 0xA0.
Offset: 0x00 (Bits[31:24]), 0x01 (bits [23:16]), 0x02 (Bits[5:8]), 0x03 (Bits[7:0]).
Location: (100 PME) -> {0xn, offset} -> 0xA0 holds the data.
