Bit Bit Name
Initial
Value R/W Description
7 RWUPE 0 R/W Remote Wakeup Detection Enable
Enables or disables the downstream port peripheral
device to use the remote wakeup function (resume
signal output) when the host controller function is
selected.
0: Downstream port remote wakeup is disabled.
1: Downstream port remote wakeup is enabled.
With this bit set to 1, on detecting the remote wakeup
signal, this module detects the resume signal (K-
state for 2.5 s) from the downstream port device
and performs the resume process (drives the port to
the K-state).
With this bit set to 0, this module ignores the
detected remote wakeup signal (K-state) from the
peripheral device connected to the downstream port.
While this bit is 1, the internal clock should not be
stopped even in the suspended state (SCKE should
be set to 1). Also note that the USB bus should not
be reset from the suspended state (USBRST should
not be set to 1); it is prohibited by USB Specification
2.0.
This bit should be set to 0 if the function controller
function is selected.
