Once STXEN is asserted, the DM9801 stops SRDCLK, asserts CRS, and toggles STDCLK.

STDCLK continues to toggle until SFD is observed, as shown in the first section on the above diagram. At this point, STDCLK
is disabled until the AID header has been transmitted on the wire or until CLS has been detected. At this time SRDCLK starts
toggling, thereby shifting 32 bits of preamble and SFD back to the MAC. Sometime later, the STDCLK restarts as symbols get
sent onto the wire in an analogous manner as SRDCLK during packet reception.
