PCI EEPROM Auto-Initialization (EEAI) [C6415 and C6416 devices only]
[The C6414 device does not support the PCI peripheral; for proper device operation, do not oppose the
internal pulldown (IPD) on the BEA13 pin.]
PCI auto-initialization via external EEPROM
0 − PCI auto-initialization through EEPROM is disabled; the PCI peripheral uses the specified
PCI default values (default).
1 − PCI auto-initialization through EEPROM is enabled; the PCI peripheral is configured
through EEPROM provided the PCI peripheral pin is enabled (PCI_EN = 1) and the
McBSP2 peripheral pin is disabled (MCBSP2_EN = 0).
Note: If the PCI peripheral is disabled (PCI_EN pin = 0), this pin must not be pulled up.
For more information on the PCI EEPROM default values, see the TMS320C6000 DSP Peripheral
Component Interconnect (PCI) Reference Guide (literature number SPRU581).
UTOPIA Enable (UTOPIA_EN) [C6415 and C6416 devices only]
[The C6414 device does not support the UTOPIA peripheral; for proper device operation, do not
oppose the internal pulldown (IPD) on the BEA11 pin.]
UTOPIA peripheral enable (functional)
BEA11
F14
0 − UTOPIA peripheral disabled (McBSP1 functions are enabled). [default]
This means all multiplexed McBSP1/UTOPIA pins function as McBSP1 and all other
standalone UTOPIA pins are tied-off (Hi-Z).
1 − UTOPIA peripheral enabled (McBSP1 functions are disabled).
This means all multiplexed McBSP1/UTOPIA pins now function as UTOPIA and all other
standalone McBSP1 pins are tied-off (Hi-Z).
