Multi-purpose input/output 15. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
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.
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.
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB.
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
JTAG Test Reset. This signal is active LOW.

Connect to VCC to enable buck regulator. Connect to GND to disable buck
regulator.
Connect these two signals together to external 4.7uH inductor.
Connect this signal to other end of external 4.7uH inductor. 47uF capacitor to
GND is also required on this pin.
Indicates that 1.2V core has been powered up.
System reset (active low). In normal operation, this signal should be HIGH.
