EM_A[0]/ IPD Selects EMIFA Pinout Mode B17 C21 I/O/Z GP[7]/(AEM2) DVDD33 The C6424 supports the following EMIFA Pinout Modes: EM_BA[0]/ IPD C17 E20 I/O/Z AEM[2:0] = 000, No EMIFA GP[6]/(AEM1) DVDD33 AEM[2:0] = 010, EMIFA (Async) Pinout Mode 2 AEM[2:0] = 101, EMIFA (NAND) Pinout Mode 5 EM_BA[1]/ IPD C16 C20 I/O/Z GP[5]/(AEM0) DVDD33 This signal doesn't actually affect the EMIFA module. It only affects how the EMIFA is pinned out. Selects the EMIFA EM_CS2 default bus width 0 = 8-bit bus width 1 = 16-bit bus width RMTXD0/GP[28]/ IPD H16 J21 I/O/Z This signal affects the EMIFA module's EM_CS2 space default (8_16) DVDD33 setting. It does not affect the pin out. To determine the actual EMIFA pinout, the (AEM[2:0]) boot configuration settings must be set appropriately. PCI Enable IPD PCIEN T3 W3 I 0 = PCI pin function is disabled DVDD33 1 = PCI pin function is enabled Endian selection RMTXD1/GP[27]/ IPU H17 L19 I/O/Z 0 = Big Endian (LENDIAN) DVDD33 1 = Little Endian Copyright © 2007–2009, Texas Instruments Incorporated Device Overview 31 Submit Documentation Feedback Product Folder Link(s): TMS320C6424 |
