38 / 146 page  TMS320C6414T, TMS320C6415T, TMS320C6416T FIXEDPOINT DIGITAL SIGNAL PROCESSORS SPRS226M − NOVEMBER 2003 − REVISED APRIL 2009 38 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 DEVICE CONFIGURATIONS (CONTINUED) Table 27. PCI_EN and MCBSP2_EN Peripheral Selection (HPI, GP[15:9], PCI, and McBSP2) PERIPHERAL SELECTION† PERIPHERALS SELECTED PCI_EN Pin [AA4] MCBSP2_EN Pin [AF3] HPI GP[15:9] PCI EEPROM (Internal to PCI) McBSP2 0 0 √ √ √ 0 1 √ √ √ 1 0 √ √ ‡ 1 1 √ √ † 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. [Note: The PCI_EN pin must be driven valid at all times and the user must not switch values throughout device operation.] 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. [Note: The PCI_EN pin must be driven valid at all times and the user must not switch values throughout device operation.] 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). [Note: The MCBSP2_EN pin must be driven valid at all times and the user can switch values throughout device operation.] other device configurations Table 28 describes the C6414T, C6415T, and C6416T 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. |
