EEPROM Chip Select
EEPROM Clock
EEPROM Data Input
EEPROM Data Output
This pin is used to determine whether Vpci or Vaux is the preferred power supply.
1=Vpci preferred, 0=Vaux preferred
General Purpose Schmitt Input/Output
General Purpose Input/Output
General Purpose Input/Output (also used for active low reset)
General Purpose Input/Output (also used for active high reset)
JTAG test data input OR general purpose input/output. Function of this pin is
dependant upon value of JTAGEN bit. When operating in JTAG mode this signal
contains serial data that is shifted in on the rising edge of TCK.
JTAG test mode select OR general purpose input/output.
Function of this pin is dependant upon value of JTAGEN bit. When operating in JTAG
mode this siganl controls the operation of the TAP controller.
TMS_GPIO[10]
I/O (PU)

I/O (PU)
JTAG reset OR general purpose input/output.
Function of this pin is dependant upon value of JTAGEN bit. When operating in JTAG
mode, a high to low transition on this signal forces the TAP controller into a logic reset
state.

JTAG clock.
JTAG data output. This pin generates serial data that is shifted out on the falling edge
of TCK..
General purpose schmitt input (modem ring detect)
General purpose schmitt input (modem offhook)
Scan chain enable. Used to shift data in and out of the scan chain.
Scan mode enable pin. When tied high it will put the device into scan test mode.
