37.6.2.11 FCTTV – Flow Control Transmit Timer Value Register
The register holds a 16-bit value in the TTV field that is inserted into a transmitted
frame (either XOFF frames or any PAUSE frame value in any software transmitted
packets). It counts in units of slot time, usually 64B. If software wishes to send an XON
frame, it must set TTV to 0 prior to initiating the PAUSE frame.
Note:
The EP80579’s GbE uses a fixed slot time value of 64B times
