Current strength of 3V LVCMOS

We are using 3VLVCMOS GPIO in cyclone 10 GX FPGA. The drive strength is mentioned as 0.1mA in datasheet and as 12mA in IO handbook. Please let us know why it is mentioned different values in datasheet and IO handbook . Please refer the attachment where i have highlighted the differences.

    Hello,

    For Table 12, to meet the IOL and IOH specifications, you must set the current strength settings accordingly. For example, to meet the 3.0-VLVTTLspecification (2 mA), you should set the current strength settings to 2 mA. Setting at lower current strength may not meet the IOL and
    IOH specifications in the datasheet.

    Table 40 is the programmable current strength control for the I/O standards.

    Thank you.
