Note:
RXCLK and TXCLK are unrelated to each other during this time. When a symbol has been received and
decoded, RXCLK toggles in order to shift out the three to six bits encoded in the symbol. The middle portion of
this diagram shows the end of the preamble, followed by an SFD and the beginning of the data. RXCRS will fall
after the last received symbol. Once RXCRS falls, RXCLK and TXCLK are toggled continuously for 96 cycles,
after which the PHY returns to the Idle state.
