Product data sheet
11.4.1 Send Resume
11.4.2 Read Current Frame Number
11.4 General commands
The microcontroller must send the Acknowledge Setup command to both the IN and OUT
endpoints.
Code (Hex) — F6
Transaction — none
Sends an upstream resume signal for 10 ms. This command is normally issued when the
device is in suspend. The Resume command is not followed by a data read or write.
Code (Hex) — F5
Transaction — read 1 or 2 B
This command is followed by one or two data reads and returns the frame number of the
last successfully received SOF. The frame number is returned least significant byte first.
