Emulation/Normal Mode [default] (see the IEEE 1149.1 JTAG
Compatibility Statement section of this data sheet)
Normal mode refers to the DSPs normal operational mode, when the DSP is free running. The
DSP can be placed in normal operational mode when the EMU[1:0] pins are configured for
either Boundary Scan or Emulation.
Note: When the EMU[1:0] pins are configured for Boundary Scan mode, the internal pulldown
(IPD) on the TRST signal must
not
be opposed in order to operate in Normal mode.
For the Boundary Scan mode pulldown EMU[1:0] pins with a dedicated 1-k
resistor.
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)
