MANAGEMENT DATA INPUT/OUTPUT (MDIO)
XSP_CLK/MDCLK§
R5
I/O/Z
IPD
PCI serial interface clock (
O
) [default] or MDIO serial clock input/output (
I/O/Z
).
XSP_DO/MDIO§
P5
I/O/Z
IPU
PCI serial interface data out (
O
) [default] or MDIO serial data input/output (
I/O/Z
). In PCI
mode, this pin is connected to the input data pin of the serial PROM.
TIMER 2
No external pins. The timer 2 peripheral pins are
not
pinned out as external pins.
TIMER 1
TOUT1/LENDIAN
B5
O/Z
IPU
Timer 1 output (
O/Z
) or device endian mode (
I
).
Also controls initialization of DSP modes at reset via pullup/pulldown resistors
Device Endian mode
0
Big Endian
1
Little Endian (default)
For more details on LENDIAN, see the Device Configurations section of this data sheet.
TINP1
I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k
IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)
§These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
PLLV is not part of external voltage supply. See the Clock PLL section for information on how to connect this pin.
#A = Analog signal (PLL Filter)
||The EMU0 and EMU1 pins are internally pulled up with 30-k
resistors; therefore, for emulation and normal operation, no external
pullup/pulldown resistors are necessary. However, for boundary scan operation, pull down the EMU1 and EMU0 pins with a dedicated 1-k
resistor.
