JSTATE
Software is required to check this bit before issuing another token command to the U1TOK register (see
Register
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.
