.1
RESUME Signal Sending Bit
0
RESUME signal is ended
1
While in suspend state, if the MCU wants to initiate a resume, it writes a 1 to
this register for 10 ms (maximum of 15 ms), and clears this register. In
suspend mode, if this bit is set to "1", USB generates resume signaling.
.0
SUSPEND Status Bit
0
Cleared automatically when MCU writes a zero to RESUME signal sending bit
or when function receives resume signal from the host while in suspend mode
1
This bit is set when SUSPEND interrupt occur
