Status information

Name	Meaning
Busy	Feedback to toggle the Execute bit. A command is currently being executed. It is necessary to wait until the device is ready. No new command can be sent or executed during this time.
Transmit	A frame is currently being sent (by manual sending or by automatic frame output ("Cyclic Frame Output" in CoE)). The frame buffer is used during sending. To prevent the frame buffer from being sent inconsistently, it is not possible to update it or trigger sending again. While the “Transmit” bit is active, commands that do not access the frame buffer can still be processed (without Update and Send).
Send Acknowledge	This toggling bit is a confirmation of the successful execution of the "Send" bit. If "Send" is executed while the "Transmit" bit was active, then the bit does not toggle.
Update Acknowledge	This toggling bit is a confirmation for the successful execution of the "Update" bit. If "Update" is executed while the "Transmit" bit was active, then the bit does not toggle.
Command Acknowledge	This toggling bit is an acknowledgement for the successful execution of the "Command".
Command Reject	If a wrong command is executed or the parameters are not correct (e.g. device is busy, length = 0, pixels addressed are outside the set Number of Pixels), the command is rejected.
