GPESTS - General Purpose Event Status (0x454)
14 P14GPEE RW 0x0
Sticky
Port 14 General Purpose Event Enable. When this bit is set,
the hot-plug INTx, MSI and PME event notification mecha-
nisms defined by the PCIe base 1.1 specification are disabled
for port 14 and are instead signalled through General Purpose
Event (GPEN) signal assertions. GPEN is an alternate func-
tion of GPIO[14].
15 P15GPEE RW 0x0
Sticky
Port 15 General Purpose Event Enable. When this bit is set,
the hot-plug INTx, MSI and PME event notification mecha-
nisms defined by the PCIe base 1.1 specification are disabled
for port 15 and are instead signalled through General Purpose
Event (GPEN) signal assertions. GPEN is an alternate func-
tion of GPIO[15].

0 Reserved RO 0x0 Reserved field.
1 P1GPES RO 0x0 Port 1 General Purpose Event Status. When this bit is set,
the corresponding port is signalling a general purpose event
by asserting the GPEN signal. This bit is never set if the corre-
sponding general purpose event is not enabled in the
GPECTL register.
GPEN is an alternate function of GPIO[5] and GPIO[5] is
asserted only if enabled to operate as an alternate function.
2 P2GPES RO 0x0 Port 2 General Purpose Event Status. When this bit is set,
the corresponding port is signalling a general purpose event
by asserting the GPEN signal. This bit is never set if the corre-
sponding general purpose event is not enabled in the
GPECTL register.
GPEN is an alternate function of GPIO[5] and GPIO[5] is
asserted only if enabled to operate as an alternate function.
3 P3GPES RO 0x0 Port 3 General Purpose Event Status. When this bit is set,
the corresponding port is signalling a general purpose event
by asserting the GPEN signal. This bit is never set if the corre-
sponding general purpose event is not enabled in the
GPECTL register.
GPEN is an alternate function of GPIO[5] and GPIO[5] is
asserted only if enabled to operate as an alternate function.
4 P4GPES RO 0x0 Port 4 General Purpose Event Status. When this bit is set,
the corresponding port is signalling a general purpose event
by asserting the GPEN signal. This bit is never set if the corre-
sponding general purpose event is not enabled in the
GPECTL register.
GPEN is an alternate function of GPIO[5] and GPIO[5] is
asserted only if enabled to operate as an alternate function.
