(Input)
New ConfigRate active
Mode input pins M[2:0] and variant select input pins VS[2:0] are sampled when INIT_B
goes High. After this point, input values do not matter until DONE goes High, at which
point these pins become user-I/O pins.
<0:0:1>
Pin initially pulled High by internal pull-up resistor if PUDC_B input is Low.
Pin initially high-impedance (Hi-Z) if PUDC_B input is High. External pull-up resistor required on CSO_B.
