Path through remote wake-up enable:
“1” is enable. If set to zero and remote wake up event occurs in suspend
state, device will drive wake up signal to Host after setting the FRWU bit in
FPCON register. Otherwise, device will drive wake up signal to Host
directly.
Device/USP Connection Pull-Up Enable:
This bit is used by FW to control whether device is connected to upper
host/hub via enable/disable the on-chip pull-up resistor. Set ‘1’ to enable
the D+ pull-up resistor; set ‘0’ to disable the D+ pull-up resistor that is
D+/D- is kept disconnected state. Default is cleared to ‘0’ after POR, FW
should set ‘1’ to enable connection to upper host/hub.
