Jumper Configuration After Power On Reset
Power pins.
Ground pins.
During power on reset duration, these pins are jumper setting pins (pull_high
= 1, pull_low = 0).
LEDDATA[0]: select SFRAM/SDRAM interface,
LEDDATA[1]: configure packet buffer size,
LEDDATA[2]: enable memory test function,
LEDDATA[3]: enable aging function,
LEDDATA[4]: enable MII polling (MDC/MDIO),
LEDDATA[5]: enable broadcast storm control,
LEDDATA[6]: enable backpressure function,
LEDDATA[7]: enable 802.3x flow control function (in full mode),
During power on reset duratoion, this in is a jumper setting pin (pull_high = 1,
pull_low = 0).
LEDCLK1: select 1K or 8K address entry table,
During power on reset duration, this in is a jumper setting pin (pull_high = 1,
pull_low = 0).
LEDCLK2: enable EEPROM interface,
During power on reset duration, this pin is a jumper setting pin (pull_high = 1,
pull_low = 0).
EEDATA: enable EEPROM auto-load configuration function while EEPROM
