39 / 146 page  TMS320C6414T, TMS320C6415T, TMS320C6416T FIXEDPOINT DIGITAL SIGNAL PROCESSORS SPRS226M − NOVEMBER 2003 − REVISED APRIL 2009 39 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 DEVICE CONFIGURATIONS (CONTINUED) Table 28. Device Configuration Pins (BEA[20:13, 9:7], HD5, and BEA11) CONFIGURATION PIN NO. FUNCTIONAL DESCRIPTION BEA20 E16 Device Endian mode (LEND) 0 – System operates in Big Endian mode 1 − System operates in Little Endian mode (default) BEA[19:18] [D18, C18] Bootmode [1:0] 00 – No boot 01 − HPI boot 10 − EMIFB 8-bit ROM boot with default timings (default mode) 11 − Reserved BEA[17:16] [B18, A18] EMIFA input clock select Clock mode select for EMIFA (AECLKIN_SEL[1:0]) 00 – AECLKIN (default mode) 01 − CPU/4 Clock Rate 10 − CPU/6 Clock Rate 11 − Reserved BEA[15:14] [D17, C17] EMIFB input clock select Clock mode select for EMIFB (BECLKIN_SEL[1:0]) 00 – BECLKIN (default mode) 01 − CPU/4 Clock Rate 10 − CPU/6 Clock Rate 11 − Reserved BEA13 B17 PCI EEPROM Auto-Initialization (EEAI) [C6415T and C6416T devices only] [The C6414T 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 0 − PCI auto-initialization through EEPROM is disabled; the PCI peripheral uses the specified PCI default 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 TMS320C6000 DSP Peripheral Component Interconnect (PCI) Reference Guide (literature number SPRU581). BEA11 D16 UTOPIA Enable (UTOPIA_EN) [C6415T and C6416T devices only] [The C6414T device does not support the UTOPIA peripheral; for proper device operation, do not oppose the internal pulldown (IPD) on the BEA11 pin .] UTOPIA peripheral enable (functional) 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 standalone McBSP1 pins are tied-off (Hi-Z). |
