FUNCTIONAL DESCRIPTION
Device endian mode (LEND)
BEA20
E16
0 – System operates in big endian mode.
1 – System operates in little endian mode (default).
Bootmode [1:0]
BEA19
BEA18
00 – No boot
D18
C18
01 – HPI boot
10 – EMIFB 8-bit ROM boot with default timings (default mode)
11 – Reserved
EMIFA input clock select. Clock-mode select for EMIFA (AECLKIN_SEL[1:0]).
BEA17
BEA16
00 – AECLKIN (default mode)
B18
A18
01 – CPU/4 clock rate
10 – CPU/6 clock rate
11 – Reserved
EMIFA input clock select. Clock-mode select for EMIFB (BECLKIN_SEL[1:0]).
BEA15
BEA14
00 – BECLKIN (default mode)
D17
C17
01 – CPU/4 clock rate
10 – CPU/6 clock rate
11 – Reserved
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
BEA13
0 – PCI auto-initialization through EEPROM is disabled; the PCI peripheral uses the specified PCI default
B17
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 PCI chapter of the TMS320C6000 Peripherals Reference Guide
(literature number SPRU190).
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.]
BEA11
UTOPIA peripheral enable (functional)
D16
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 stand-alone McBSP1 pins are tied off
(Hi-Z).

HPI peripheral bus width (HPI_WIDTH)
HD5
0 – HPI operates as an HPI16.
Y1
(HPI bus is 16 bits wide. HD[15:0] pins are used and the remaining HD[31:16] pins are reserved pins in
the Hi-Z state.)
1 – HPI operates as an HPI32.
(HPI bus is 32 bits wide. All HD[31:0] pins are used for host-port operations.)
(1) For proper device operation, this pin must be externally pulled up with a 1-kΩ resistor.
