    Hi Jiawei,

    The delay of the BC GPIO is calculated using the time it takes for a BC frame to travel across the link. In the worst case scenario, BC information will take 2 frames to transmit.

    BC_Delay =  30 [bits/frame] / BC frequency [bits/sec]

    BC_Delay (Worst Case) = 30 [bits/frame] / BC frequency [bits/sec] * 2
