    # Sleep clock accuracy (sca). This is the amount of drift in the system
    # during when the device is sleeping (in parts per million).
    #
    # NOTE: 'the' master sca is an enumerated value based on the sca. Rather
    # than have a piece of code calculate this value, the developer must set
    # this value based on the value of the SCA using the following table:
    #
    #  SCA between 251 and 500 ppm (inclusive); master sca = 0
    #  SCA between 151 and 250 ppm (inclusive); master sca = 1
    #  SCA between 101 and 150 ppm (inclusive); master sca = 2
    #  SCA between 76 and 100 ppm (inclusive); master sca = 3
    #  SCA between 51 and 75 ppm (inclusive); master sca = 4
    #  SCA between 31 and 50 ppm (inclusive); master sca = 5
    #  SCA between 21 and 30 ppm (inclusive); master sca = 6
    #  SCA between 0 and 20 ppm (inclusive); master sca = 7

            (depending on when the next scheduled event occurs and how much data needs
            to be transferred in the connection). However, you will be guaranteed that

            connection is created. However, older TI CC254x controllers cannot change
            connection parameters later if WindowOffset was set to 0 in CONNECT_IND. To
