Software is required to check this bit before issuing another token command to the U1TOK register (see
Register 10-15).
All host control logic is reset any time that the value of this bit is toggled.
Software must set RESUME for 10 ms if the part is a function, or for 25 ms if the part is a host, and then
clear it to enable remote wake-up. In Host mode, the USB module will append a low-speed EOP to the
RESUME signaling when this bit is cleared.
Device mode.
Host mode.
