The core has been configured to have one FFT data channel and overflow. The current frame contains no overflow.

Field Name Padding Value
OVFLO (channel 0) None 0

This gives a vector length of 1 bit. As all AXI channels must be aligned to byte boundaries, 7 padding bits are required, giving an m_axis_status_tdata length of 8 bits.
