HI 

If we are using COL pin as MLED function , do we need to provide the 2.2K pull up/down parallel to the current limiting resistor of LED

    Hi Eby,

    The PU/PD resistor ratios (Table 8-8) will depend on the strapping configuration you want to use, see Table 8-10 for more information on strapping the COL pin.

    The MLED function can be programmed through register access (0x0025, Table 8-44).  

    Section 8.5.2 might lend additional information if needed.

    Regards,

    Alvaro
