2.7 Terminal Functions
The terminal functions table (Table 2-5) identifies the external signal names, the associated pin (ball)
numbers along with the mechanical package designator, the pin type (I, O/Z, or I/O/Z), whether the pin
has any internal pullup/pulldown resistors and a functional pin description. For more detailed information
on device configuration, peripheral selection, multiplexed/shared pins, and debugging considerations, see
Section 3.

DESCRIPTION
NAME NO.
CONFIGURATION PINS
MACSEL0[0] AE6 I IPD
MACSEL0[1] AG5 I IPD EMAC0 configuration select pin (for details, see Table 3-1).
MACSEL0[2] AF6 I IPD
Device Endian pin.
LENDIAN AH4 I IPU 0 = System operates in Big-Endian mode
1 = System operates in Little-Endian mode (default)
MACSEL1[0] AF5 I IPD
EMAC1 configuration select pin (for details, see Table 3-1).
MACSEL1[1] AH5 I IPD
DDR2 Memory Controller enable
DDREN E20 I IPD 0 = disabled (only use this mode if DDR is not powered)
1 = enabled
RapidIO enable
RIOEN U26 I IPD 0 = disabled (only use this mode if RapidIO is not powered)
1 = enabled
HOST EVENT PINS
HOUT AH23 O/Z IPU Host event output.
GENERAL-PURPOSE INPUT/OUTPUT PINS
General-purpose input/output pin 0 multiplexed with HPI internal
pulls enable/disable
0 = Internal pulls on HPI IO are enabled and buffers are turned
GP00/HPI_EN M1 I/O/Z IPD off.
1 = Internal pulls on most HPI IO are disabled and all buffers are
turned on.
For more detail about internal pull options, see Section 3.3.1.
General-purpose input/output pin 1 multiplexed with UTOPIA
internal pulls enable/disable
0 = Internal pulls on UTOPIA IO are enabled and buffers are
GP01/UTOPIA_EN N5 I/O/Z IPD turned off.
1 = Internal pulls on UTOPIA IO are disabled and buffers are
turned on.
For more detail about internal pull options, see Section 3.3.1.
GP02/TSIP0_EN M3 I/O/Z IPD General-purpose input/output pin [4:2] multiplexed with TSIP[2:0]
internal pulls enable/disable
GP03/TSIP1_EN K5 I/O/Z IPD
0 = Internal pulls on TSIPx IO are enabled and buffers are turned
off.
1 = Internal pulls on TSIPx IO are disabled and buffers are turned
GP04/TSIP2_EN M5 I/O/Z IPD
on.
For more detail about internal pull options, see Section 3.3.1.
General-purpose input/output pin 5 multiplexed with EMAC1
internal pulls enable/disable
0 = Internal pulls on EMAC1 IO are enabled and buffers are
GP05/EMAC1_EN N4 I/O/Z IPD turned off.
1 = Internal pulls on EMAC1 IO are disabled and buffers are
turned on.
For more detail about internal pull options, see Section 3.3.1.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the
opposite supply rail, a 1-kΩ resistor should be used.)
(3) IPU/IPD logic on some pins can be disabled based on configuration. For more information, see .
