Multifunction pin: MS UART mode select (1MΩ pull-down; low=Base, high=Bypass), VS or DE/DV video monitor push-pull output, FSYNC push-pull output, or GPIO0. GMSL1 functions also include FSYNC_IN/OUT (frame-sync input with 1MΩ pull-down to ground or frame-sync push-pull output) and CNTL1 push-pull output. MAX96714F power-up default is GPI0 with 1MΩ pull-down. GPIO supports configurable input, push-pull output, or open-drain output and programmable 40kΩ/1MΩ pull-up, pull-down, or no pull.
