  • hi:
    we want to manual control UCD90124N GPIO13 via I2C, Could provide control steps. as in my application gpio13(rail5,page 4) is depend on mon5, when i manually change the output of gpio13, the mon5 will be changed and the chip will be reset. so i need to shutdown the mon5's function. but i can't execute write MONITOR_CONFIG, but i can read MONITOR_CONFIG command correctly!
  • Hi,

    This question has been answered offline to Brian Zhao.

    We do not suggest change MON pin or GPIO configuration on-the-fly. This can cause unexpected behavior.

    The suggested method is to change the rail's ON_OFF_CONFIG to OPERATION, then send an OPERATION command to turn off the rail. After turning the rail back on, change the rail's ON_OFF_CONFIG to the original state.
