This bit is set to 1 while the USB hardware is in the suspended state. This bit is a firmware
read only bit. It is set and cleared by the USB hardware.
Bit 3
–
RESUME FLGL Resume Flag
When the USB hardware receives a resume signal from the upstream device it sets this bit.
This bit will stay set until the USB hardware completes the downstream resume signaling. This
bit is a firmware read only bit. It is set and cleared by the USB hardware.
Bit 2
–
Reserved
This bit is reserved in the AT43USB351M and will read as zero.
