Notes: *2. Do not pull pin143 WAKEUP_OUT to high; otherwise boot will fail.
*3. Pull Pin144 WAKEUP_IN to VREF with a 100k resistor and keep it high before
system boot process is complete.
*4. Pull pin142 POWER_ON to VREF with a 100k resistor for stability considerations.
*5. Refer to SGMII standard for more electronic characteristics.
*6. Refer to section 2.3, for more information please check USB2.0 standard
*7. Pull pin87 USB detect to VREF with a 100k resistor to enable module USB, pull
pin87 low to disable module USB, CPU USB PHY consumes some current when
USB is enabled.
*8. Do not pull pin52 to high before the system boot process is complete.
*9. Leave unused pins floating
