PUDC_B
New ConfigRate active
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.
Mode input pins M[2:0] are sampled when INIT_B goes High. After this point,
input values do not matter until DONE goes High, at which point the mode pins
become user-I/O pins.
