Note:
1. The Main column is the main function, Alt. Means alternative function.
2. The multi-function GPIO pins are set to
green characters .
3. The video input port and external TV encoder mode can not both use CCIR-601 mode, at least one of them
should be in CCIR-656 mode.
4. Following is a summary of modified pins.
(a) Pin 44, 45, 153, 154, 171, 172, 175, 180, 181, 183, 184, 185, 186, 187, 188, 240, 242, 243, 250, 251 are
NC pins.
(b) Pin 114, 136, 168, 169, 170, 174, 176, 177, 178, 179 will be used as GPIO only.
(c) Pin 48, 49, 50, 51 are no longer for JTAG functions.
(d) V_ADIN3 (pin 153) is not available.
(e) Pin 43 used as 1.8V ground pin for internal digital circuitry. Pin 46 used as 3.3V power pin for internal
digital circuity.
