NO. Standalone GPIO 3.3 V GP[22]/ IPD F18 J20 I/O/Z (BOOTMODE0) DVDD33 GP[23]/ IPD F15 K20 I/O/Z (BOOTMODE1) DVDD33 These pins function as boot configuration pins during device reset. GP[24]/ IPD G15 L20 I/O/Z After device reset, these pins function as standalone general-purpose (BOOTMODE2) DVDD33 input/output (GPIO). GP[25]/ IPD G16 H21 I/O/Z (BOOTMODE3) DVDD33 GP[26]/ IPD G17 K19 I/O/Z (FASTBOOT) DVDD33 IPD GP[53] A13 A17 I/O/Z This pin is standalone and functions as GPIO pin 53. DVDD33 IPD GP[54] A14 A18 I/O/Z This pin is standalone and functions as GPIO pin 54. DVDD33 (1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal (2) IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown resistors are required, see Section 3.9.1 , Pullup/Pulldown Resistors. (3) Specifies the operating I/O supply voltage for each signal 58 Device Overview Copyright © 2007–2009, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TMS320C6424 |
