Pin initially pulled High by internal pull-up resistor if HSWAP input is Low.
Pin initially high-impedance (Hi-Z) if HSWAP input is High. External pull-up resistor required on CSO_B.
<1:1:1>
<0:0:1>
HSWAP must be stable before INIT_B goes High and constant throughout the configuration process.

Command
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.
