2.7 Terminal Functions
TMS320TCI6482
Communications Infrastructure Digital Signal Processor
SPRS246F–APRIL 2005–REVISED MAY 2007
The terminal functions table (
Table 2-3
) 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 pullup/pulldown resistors, see
Section 3
,
Device Configuration

DESCRIPTION
NO.
CLOCK/PLL CONFIGURATIONS
IPD
Clock Input for PLL1.
IPD
Clock Input for PLL2.
1.8-V I/O supply voltage for PLL1
1.8-V I/O supply voltage for PLL2
SYSCLK4 is the clock output at 1/8 of the device speed (
O/Z
) or this pin can be
IPD
programmed as the GP1 pin (
I/O/Z
) [default].

IPD = Internal pulldown, IPU = Internal pullup. For most systems, a 1-k
resistor can be used to oppose the IPU/IPD. For more detailed
information on pullup/pulldown resistors and situations where external pullup/pulldown resistors are required, see
Section 3.7
,
Pullup/Pulldown Resistors
.
These pins are multiplexed pins. For more details, see
Section 3
,
Device Configuration
.
The TCI6482 DSP does not require external pulldown resistors on the EMU0 and EMU1 pins for normal or boundary-scan operation.
