DEVICE CONFIGURATIONS
The C6414T, C6415T, and C6416T device configurations are determined by external pullup/pulldown resistors
on the following pins (all of which are latched during device reset):
peripherals selection (C6415T and C6416T devices)
BEA11 (UTOPIA_EN)
PCI_EN (for C6415T or C6416T, see Table 27 footnotes)
MCBSP2_EN (for C6415T or C6416T, see Table 27 footnotes)
The C6414T device does
not
support the PCI and UTOPIA peripherals; for proper operation of the C6414T
device, do
not
oppose the internal
pulldowns
(IPDs) on the BEA11, PCI_EN, and MCBSP2_EN pins. (For
IPUs/IPDs on pins, see the Terminal Functions table of this data sheet.)
other device configurations (C64x)
BEA[20:13, 7]

peripherals selection
Some C6415T/C6416T peripherals share the same pins (internally muxed) and are mutually exclusive (i.e.,
HPI, general-purpose input/output pins GP[15:9], PCI and its internal EEPROM, McBSP1, McBSP2, and
UTOPIA). The VCP/TCP coprocessors (C6416T only) and other C64x peripherals (i.e., the Timers, McBSP0,
and the GP[8:0] pins), are always available.
UTOPIA and McBSP1 peripherals
The UTOPIA_EN pin (BEA11) is latched at reset. For C6415T and C6416T devices, this pin selects whether
the UTOPIA peripheral or McBSP1 peripheral is functionally enabled (see Table 26).
The C6414T device does
not
support the UTOPIA peripheral; for proper device operation, do
not
oppose
the internal
pulldown
(IPD) on the BEA11 pin.

DESCRIPTION
0
√
McBSP1 is enabled and UTOPIA is disabled [default].
This means all multiplexed McBSP1/UTOPIA pins function as McBSP1
and all other standalone UTOPIA pins are tied-off (Hi-Z).
1
√
UTOPIA is enabled and McBSP1 is disabled.
This means all multiplexed McBSP1/UTOPIA pins now function as
UTOPIA and all other standalone McBSP1 pins are tied-off (Hi-Z).
HPI, GP[15:9], PCI, EEPROM (internal to PCI), and McBSP2 peripherals
The PCI_EN and MCBSP2_EN pins are latched at reset. They determine specific peripheral selection for
the C6415T and C6416T devices, summarized in Table 27.
The C6414T device does
not
support the PCI peripheral; for proper device operation, do
not
oppose the
internal pulldowns (IPDs) on the PCI_EN and MCBSP2_EN pins.
