The following document:
TMS320C28x DSP CPU and Instruction Set (Rev. F)
Reference Guide: http://www.ti.com/litv/pdf/spru430f
Mentions about an "IDLE output" in section 6.3, page 198, item 5. I could not find references to that output in the datasheets at which I have looked, particularly the F28335. Could you please confirm whether this information is inherited from an older document or whether that output indeed exists?
I am aware of the clock output in idle mode, but the note mentions about an active high output, possibly suggesting that a GPIO could be dedicated to idle mode indication.
Thank you!
