DEVICE CONFIGURATIONS
The C6414, C6415, and C6416 peripheral selections and other device configurations are determined by
external pullup/pulldown resistors on the following pins (all of which are latched during device reset):
D peripherals selection (C6415 and C6416 devices)
− BEA11 (UTOPIA_EN)
− PCI_EN (for C6415 or C6416, see Table 27 footnotes)
− MCBSP2_EN (for C6414 or C6416, see Table 27 footnotes)
The C6414 device does not support the PCI and UTOPIA peripherals; for proper operation of the C6414
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.)
D other device configurations (C64x)
− BEA[20:13, 7]
− HD5
peripherals selection
Some C6415/C6416 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 (C6416 only) and other C64x peripherals (i.e., the Timers, McBSP0, and the
GP[8:0] pins), are always available.
D UTOPIA and McBSP1 peripherals
The UTOPIA_EN pin (BEA11) is latched at reset. For C6415 and C6416 devices, this pin selects whether
the UTOPIA peripheral or McBSP1 peripheral is functionally enabled (see Table 26).
The C6414 device does not support the UTOPIA peripheral; for proper device operation, do not oppose the
internal pulldown (IPD) on the BEA11 pin.

DESCRIPTION
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).
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).
D 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 C6415 and C6416 devices, summarized in Table 27.
The C6414 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.
