The PCI_EN pin
must
be driven valid at all times and the user
must not
switch values throughout device operation.
The MCBSP2_EN pin
must
be driven valid at all times and the user
can
switch values throughout device operation.
The only time McBSP2 is disabled is when both PCI_EN = 1 and MCBSP2_EN = 0. This configuration enables, at reset, the auto-initialization
of the PCI peripheral through the PCI internal EEPROM [provided the PCI EEPROM Auto-Initialization pin (BEA13) is pulled up
(EEAI = 1)]. The user can then enable the McBSP2 peripheral (disabling EEPROM) by dynamically changing MCBSP2_EN to a “1” after the
device is initialized (out of reset).
If the PCI is disabled (PCI_EN = 0), the HPI peripheral is enabled and GP[15:9] pins can be programmed
as GPIO, provided the GPxEN and GPxDIR bits are properly configured.
This means all multiplexed HPI/PCI pins function as HPI and all standalone PCI pins (PCBE0 and
XSP_CS) are tied-off (Hi-Z). Also, the multiplexed GPIO/PCI pins can be used as GPIO with the
proper software configuration of the GPIO enable and direction registers (for more details, see
Table 29).
If the PCI is enabled (PCI_EN = 1), the HPI peripheral is disabled.
This means all multiplexed HPI/PCI pins function as PCI. Also, the multiplexed GPIO/PCI pins function
as PCI pins (for more details, see Table 29).
The MCBSP2_EN pin, in combination with the PCI_EN pin, controls the selection of the McBSP2
peripheral and the PCI internal EEPROM (for more details, see Table 27 and its footnotes).
other device configurations
Table 28 describes the C6414, C6415, and C6416 devices configuration pins, which are set up via external
pullup/pulldown resistors through the specified EMIFB address bus pins (BEA[20:13, 11, 9:7]) and the HD5 pin.
For more details on these device configuration pins, see the Terminal Functions table and the Debugging
Considerations section.
