EEPROM SIGNALS
EECK
P13
O
Serial clock to EEPROM. An internal clock of CLK divide by 256 is used for
reading the vendor and sub-vendor ID during power up or reset. However, it
can be manually clocked thru the Configuration Register REGB.
EECS
R14
O
Chip select to a EEPROM device like 93C46. It is manually selectable thru
the Configuration Register REGB. Requires a pull-up 4.7K ohm resistor for
external sensing of EEPROM during power up.
EEDI
P14
O
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB.
EEDO
M12
I
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
JTAG SIGNALS
TRST#
N4
I
JTAG Test Reset. This signal is active LOW.
