JP1 :
a)Flash memory(U5) : 1-3 short only
b)External SRAM( J16) : 1-2 and 3-4 short
When using INTEL FLASH:
R219=0 ohm, R210=NC
When using SST FLASH:
R210=0 ohm, R219=NC
Default is SST mode.
Flash speed <= 70 nS
EXTERNAL SRAM PORT
ONLY FOR DEBUG
Add RN8,RN4,RN2,RN5,RN3,RN6,RN7,RN9 for EMI improvment.
