YOUT3/ IPD R3/ D18 I/O/Z DVDD18 AEAW3 YOUT4/ IPD R4/ E15 I/O/Z DVDD18 AEAW4 YOUT5/ E16 O DVDD18 Video encoder output YOUT5 or RGB666/888 Red data bit 5 output R5. R5 YOUT6/ E17 O DVDD18 Video encoder output YOUT6 or RGB666/888 Red data bit 6 output R6. R6 YOUT7/ E18 O DVDD18 Video encoder output YOUT7 or RGB666/888 Red data bit 7 output R7. R7 GPIO0/ This pin is multiplexed between GPIO and the VPBE. C13 I/O/Z DVDD18 LCD_OE In VPBE mode, it is the LCD output enable LCD_OE. GPIO2/ This pin is multiplexed between GPIO and the VPBE. D13 I/O/Z DVDD18 G0 In VPBE mode, it is RGB888 Green data bit 0 output G0. (1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal (2) IPD = Internal pulldown, IPU = Internal pullup. (To pull up a signal to the opposite supply rail, a 1-k Ω resistor should be used.) (3) Specifies the operating I/O supply voltage for each signal 44 Device Overview Copyright © 2005–2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TMS320DM6446 |
