FIR filter with FDAtool using the order number and the cut-off frequency

Hi all,
I need to design an FIR high-pass filter to attenuate frequencies from 20Hz and below. I need the order to be around 8 since I will be implementing the filter on a microcontroller. When using FDAtool, there are only Fpass and Fstop as the input parameters. Is there an option to input Fc? or is there a way to determine Fpass and Fstop from the order number and the cut-off frequency?
