TFCLK TFCLK D7
To achieve maximum bandwidth, set
TFCLK as follows:
MPHY: 133 Mhz
SPHY: 125 Mhz.
TPRTY_0 TPRTY_0 D5
MPHY: Use TPRTY_0 as the TPRTY
signal.
SPHY: Each port has its own dedicated
TPRTY_n signal.

GND TPRTY_2 B9
GND TPRTY_3 J6
TENB_0 TENB_0 B7
MPHY: Use TENB_0 as the TENB
signal.
SPHY: Each port has its own dedicated
TENB_n signal.
