30 / 269 page  TMS320C6472 SPRS612G – JUNE 2009 – REVISED JULY 2011 www.ti.com Table 2-5. Terminal Functions (continued) SIGNAL TYPE(1) IPD/IPU(2) (3) DESCRIPTION NAME NO. GP06/BOOTMODE0 L5 I/O/Z IPU General-purpose input/output pin [9:6] multiplexed with GP07/BOOTMODE1 L4 I/O/Z IPU BOOTMODE selection pin [3:0] (for details, see Table 3-1 and GP08/BOOTMODE2 K3 I/O/Z IPU Section 2.4). GP09/BOOTMODE3 K4 I/O/Z IPU GP10/CFGGP0 M2 I/O/Z IPD GP11/CFGGP1 N3 I/O/Z IPD General-purpose input/output pin [14:10] multiplexed with GP12/CFGGP2 M4 I/O/Z IPD configuration selection pin [4:0]. GP13/CFGGP3 L1 I/O/Z IPD GP14/CFGGP4 L2 I/O/Z IPD General-purpose input/output pin 15 multiplexed with SYSCLKOUT enable. GP15/SYSCLKOUTEN L3 I/O/Z IPD 0 = SYSCLKOUT is disabled (default) 1 = SYSCLKOUT is enabled DDR2 MEMORY CONTROLLER BSDDQM3 C16 O/Z DDR2 Memory Controller byte-enable controls • Decoded from the low-order address bits. The number of BSDDQM2 B15 O/Z address bits or byte enables used depends on the width of BSDDQM1 G4 O/Z external memory. • Byte-write enables for most types of memory. BSDDQM0 A3 O/Z • Can be directly connected to SDRAM read and write mask signal (SDQM). BCS1 E9 O/Z DDR2 Memory Controller memory space enable. When the DDR2 Memory Controller is enabled, it first sets these pins low. Then as accesses occur to the DDR2 memory, only the chip select BCS0 A4 O/Z corresponding to the accessed DDR2 memory is low. BBA2 A6 O/Z BBA1 B6 O/Z DDR2 Memory Controller bank address control BBA0 C7 O/Z BEA00 B12 BEA01 A12 BEA02 A11 BEA03 B11 BEA04 C11 BEA05 D11 BEA06 A9 O/Z DDR2 Memory Controller address bus BEA07 C10 BEA08 D10 BEA09 C9 BEA10 B8 BEA11 A7 BEA12 B7 BEA13 D9 BECLKOUTP C8 O/Z DDR2 Memory Controller output clock (CLKIN3 frequency × 10) - differential output BECLKOUTN D8 O/Z 30 Device Overview Copyright © 2009–2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s) :TMS320C6472 |
