3. Resume K: When the host wants to wake up the peripheral, it sets OPMODE[1:0] to
10b and transmits a K for at least 20 ms. The peripheral link sees the resume K on
LINESTATE, and asserts STP to wake up the PHY.
4. EOP: When STP is asserted, the ISP1507 on the host side automatically appends an
EOP of two bits of SE0 at low-speed bit rate, followed by one bit of J. The ISP1507 on
the host side knows to add the EOP because DP_PULLDOWN and DM_PULLDOWN
are set to 1b for a host. After the EOP is completed, the host link sets OPMODE[1:0]
to 00b for normal operation. The peripheral link sees the EOP and also resumes
normal operation.
