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.
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.
O Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB.
I Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
I JTAG Test Reset. This signal is active LOW.

I Connect to VCC to enable buck regulator. Connect to GND to disable buck
regulator.
