Description
Reserved. Read returns zero.
PME# status (R/W-clear: default 0b). Set when an event causes PME# to be
asserted independent of the state of PMEEN bit. Writing a 1 to this bit clears it
and deasserts the PME# signal if enabled. Writing a 0 has no effect. Since the
PC-TEL HSP modem module supports PME# from D3cold, this bit must be
explicitly cleared by the OS each time it is initially loaded.
Reserved. Read returns zero.
PME# enable (R/W: default 0b). When set, enables PME# to be asserted. Other-
wise PME# assertion is disabled. Since the PC-TEL HSP modem module sup-
ports PME# from D3cold, this bit must be explicitly cleared by the OS each time it
is initially loaded.
Reserved. Read returns zero.
Power state (R/W: default 11b). Used to determine the current power state of the
PC-TEL HSP modem module and to set it into a new power state. Supported
field values are shown below. Software attempts to write an unsupported state to
this field have no effect.
