HOST Reference Clock
HCLK is determined by the strapping pins in SYSLED[3:1], i.e. the jump
selection of J1[5-6, 3-4, 1-2]:
J1[OFF,OFF,OFF]
J1[ OFF,OFF, ON]
J1[OFF, ON, OFF]
J1[OFF, ON, ON]
J1[ ON,OFF,OFF]
SYSTEM RESET
SYSTEM Output Pins for LED:
SYSLED[8:0] are connected to pull-up IO PADs for strapping.
SYSLED[25:9] are connected to IO PADs without pull up/down.
All SYSLED[25:0] are
