VCC POR
Bit[0] PME_Status
= 0 (default)
= 1 Set when LPC47M172 would normally assert the nIO_PME signal,
Bit[7:1] Reserved
PME_Status is not affected by Vcc POR, SOFT RESET or HARD RESET.
Writing a “1” to PME_Status will clear it and cause the LPC47M172 to stop
asserting nIO_PME, in enabled. Writing a “0” to PME_Status has no effect.
Bits[7:0] Reserved – reads return 0
Bit[0] PME_En
= 0
= 1
Bit[7:1] Reserved
PME_En is not affected by Vcc POR, SOFT RESET or HARD RESET
Bits[7:0] Reserved – reads return 0
