26 / 214 page  TMS320C6474 SPRS552H – OCTOBER 2008 – REVISED APRIL 2011 www.ti.com 2.7 Terminal Functions The terminal functions table (Table 2-5) identifies the external signal names, the pin type (I, O, O/Z, or I/O/Z), whether the pin has any internal pullup/pulldown resistors, and the signal function description. Table 2-5. Terminal Functions SIGNAL TYPE(1) IPD/IPU(2) SIGNAL DESCRIPTION NAME NO. ANTENNA INTERFACE AIFRXN0 AF22 I AIFRXP0 AF21 I AIFRXN1 AG20 I AIFRXP1 AG21 I AIFRXN2 AG18 I AIFRXP2 AG17 I Antenna Interface Receive Data (6 links) AIFRXN3 AE17 I AIFRXP3 AE18 I AIFRXN4 AE14 I AIFRXP4 AE13 I AIFRXN5 AF12 I AIFRXP5 AF13 I AIFTXN0 AE21 O AIFTXP0 AE22 O AIFTXN1 AD21 O AIFTXP1 AD20 O AIFTXN2 AF16 O AIFTXP2 AF17 O Antenna Interface Transmit Data (6 links) AIFTXN3 AD17 O AIFTXP3 AD16 O AIFTXN4 AG13 O AIFTXP4 AG14 O AIFTXN5 AD13 O AIFTXP5 AD12 O CLOCK/RESETS NMI0 J4 I IPD Non-maskable interrupts. NMI0, NMI1, and NMI2 pins are mapped to C64x+ Megamodule Core 0, C64x+ Megamodule Core 1, and C64x+ Megamodule Core NMI1 J2 I IPD 2, respectively. NMIs are edge-driven (rising edge). Any noise on the NMI pin NMI2 J1 I IPD may trigger an NMI interrupt; therefore, if the NMI pin is not used, it is recommended that the NMI pin be grounded rather than relying on the IPD.

All internal pullups and pulldowns are 100 μA. 26 Device Overview Copyright © 2008–2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s) :TMS320C6474 |
