Bit 6 PRES: Port resume
Bit 5 POCCHNG: Port overcurrent change

Bit 2 PENA: Port enable
Bit 1 PCDET: Port connect detected
Bit 0 PCSTS: Port connect status
The application sets this bit to drive resume signaling on the port. The core continues to drive
the resume signal until the application clears this bit.
If the core detects a USB remote wakeup sequence, as indicated by the Port resume/remote
wakeup detected interrupt bit of the Core interrupt register (WKUINT bit in
OTG_FS_GINTSTS), the core starts driving resume signaling without application intervention
and clears this bit when it detects a disconnect condition. The read value of this bit indicates
whether the core is currently driving resume signaling.
The core sets this bit when the status of the Port overcurrent active bit (bit 4) in this register
changes.
Indicates the overcurrent condition of the port.
The core sets this bit when the status of the Port enable bit [2] in this register changes.
A port is enabled only by the core after a reset sequence, and is disabled by an overcurrent
condition, a disconnect condition, or by the application clearing this bit. The application cannot
set this bit by a register write. It can only clear it to disable the port. This bit does not trigger
any interrupt to the application.
The core sets this bit when a device connection is detected to trigger an interrupt to the
application using the Host port interrupt bit in the Core interrupt register (HPRTINT bit in
OTG_FS_GINTSTS). The application must write a 1 to this bit to clear the interrupt.
